New RF Shielded Room in the UK

Global EMC have completed another RF shielded room (Faraday cage) in the United Kingdom. The multi-functional RF room shall be used for variety of uses including conductive testing, inert RF environment as well as an education and experimentation facility.

 

The shielded room of external dimensions 6.0m (L) x 4.2m (W) x 3.0m (H) effortlessly integrated into the host building to provide a suitable and attractive external finish for the environment it was installed in.

The shielding was independently tested and exceeded -100dB of shielding from 100 kHz to 18 GHz and greater than -65dB all the way down to 10 kHz.

The facility was provided with a penetration panel providing connection from the external host building to inside the room in a convenient and controlled manor. Precision connectors where used and optical fibre and data waveguides also provided. This ensured the client had not only the required connectivity currently but also future proofed the facility going forward.

 

The easy to open manual swing door provided access into the shielded room whilst maintaining the high levels of required shielding. Low maintenance low friction door furniture means the door is both practical and easy to maintain for the user.

 

Internally the room benefits from a high aesthetic “office style” finish. This provides a comfortable environment for staff to work inside. This includes a suspended ceiling, raised false floor and melamine boarded walls. Creating a decorative, functional and durable finish to the room.


TII Unveils the Arab World’s First Electromagnetic Compatibility Labs

TII Unveils the Arab World’s First Electromagnetic Compatibility Labs


Arab World’s First Electromagnetic Compatibility Labs

ABU DHABI, United Arab Emirates -Technology Innovation Institute (TII), the applied research pillar of the Advanced Technology Research Council (ATRC), announced that its Directed Energy Research Centre (DERC) has unveiled its Electromagnetic Compatibility (EMC) laboratories in Abu Dhabi, housed in a first of its kind facility in the Arab world.

 

The facility is composed of three laboratories - an
- EMC semi-anechoic chamber
- A pulsed power laboratory
- Low-noise emanation laboratory.

 

The DERC facility enables key technologies to be evaluated against electromagnetic compatibility and interference by reproducing man-made and natural electromagnetic hazards in the pulsed power and semi-anechoic chambers.

 

The direct connection between the two chambers enables a diversity of experiments involving 100’s of kV nanosecond pulses and multi-megawatt microwaves systems. The laboratories have been designed to host different categories of equipment such as connected objects of the Internet of Things, drones and autonomous cars, telecommunications equipment, medical devices, automotive equipment, IT equipment and is fully automated for tests and measurements.

 

A unique low-noise emanation lab has been built on DERC specifications that allow for the study of very low noises emitted by electronic systems.

Dr Chaouki Kasmi, Chief Researcher at Directed Energy Research Centre

“At DERC we support research on a wide range of topics in EMC and EMI on behalf of governments and enterprises to help create and maintain advanced electronic systems. We are excited to announce the launch of the EMC labs in Abu Dhabi. They will help in pre-qualification of electronics against Electromagnetic Compatibility and Interference Standards as well as hardening of critical infrastructures to operate safely in harsh environments.”

 

Many electromagnetic compatibility standards have been introduced over the years, making EMC a key part of the electronics design process, Dr Kasmi said. With standards now implemented and enforced globally, manufacturers have to ensure that new electronic products meet the relevant EMC standards.

 

“There is growing awareness that high standards of electromagnetic compatibility must be maintained. So electromagnetic compatibility must be achieved right from the start, which underscores the importance of the launch of our labs,” Dr Kasmi added.

The Climate Pledge

The Climate Pledge


Global EMC have signed up to the challenge

What is the Climate Pledge?

The Climate Pledge, with its bold goal of net zero carbon by 2040—ten years earlier than specified by the Paris Agreement—presents a leadership opportunity for companies around the world to join together in taking urgent action on the climate crisis. Amazon co-founded The Climate Pledge with Global Optimism in 2019, and became the first company to sign the pledge. The Climate Pledge currently has over 100 signatories, including Verizon, PepsiCo, Best Buy, Visa, Reckitt Benckiser (RB), Microsoft, Unilever, JetBlue Airways, Uber, and more.

What does it mean to join The Climate Pledge?

The Climate Pledge calls on signatories to be net zero carbon across their businesses by 2040. Companies that sign the pledge commit to three principal areas of action:

 

• Measure and report greenhouse gas emissions on a regular basis;
• Implement decarbonization strategies in line with the Paris Agreement through real business changes and innovations, including efficiency improvements, renewable energy, materials reductions, and other carbon emission elimination strategies;
• Neutralize any remaining emissions with additional, quantifiable, real, permanent, and socially-beneficial offsets to achieve net zero annual carbon emissions by 2040.

Net Zero Carbon by 2040

It's time to make carbon history

Businesses are taking on the greatest challenge humanity has ever faced.

We’re turning the climate crisis into climate action, reaching the goals of the Paris Agreement 10 years early.

We won't get there without changing the way we do business.

1. Use wind, or solar....or both
2. Why don't you plant more trees instead of cutting them down
3. Do more sustainable farming, its a thing now.
4. Go all-electric faster, I dare you.
5. Protect my water

Shielded Room Faraday cage for R&D

Shielded Room Faraday cage for R&D.

A large international company approached Global EMC to build them a shielded room Faraday cage to enable them to perform testing in an inert environment free from mobile, radio and WiFi signals.

 

The self-supporting enclosure was constructed using Global EMC’s “pan” type shielding solution. The high performance shielding gave the client greater than -100dB of shielding from 100 MHz to 18 GHz as tested by an independent test laboratory.

 

The room had a high aesthetic internal finish to provide an office style environment within the shielding. Small power, lighting, and data where all provided to make the room versatile and future proof.

 

The chamber also had an internally switchable "in use" light above the door to enable staff to visually see when not to enter the room during testing.


Wedge Absorber

Wedge Absorber for Anechoic Chambers

Wedge absorbers give around 20% more anechoic performance than full peak absorbers at frequencies below 1 GHz, due to their greater mass. The wedge system is used where a low-frequency bias is required.

 

Using the 20% mass the Wedge absorber system can save money by using smaller pyramids and the microwave performance is excellent with a return loss of -40dB at 8 x wavelength.

 

Global EMC’s wedge pyramid absorber gives excellent performance in compact chambers. The absorber fully complies with NRL 8093 parts I, II and III Fire safety standard.
