If we credit the integrated circuit with one thing, it should be the taming of the electromagnetic spectrum. If you want to create or capture visible photons, there are plenty of compact devices to choose from, incorporating everything from miniature photodiodes and lasers to LEDs and slim charge-coupled devices. And if you want to pick up or send a radio signal, there are a staggering number of receivers, transmitters, and antennas to suit your needs.

But the IC hasn't conquered every bit of the spectrum, and one region stands out: the terahertz frontier, a range that extends from the highest frequency radio waves to the lowest frequency infrared light. Over the decades, engineers have made many attempts to create compact, solid-state devices that can harness it, but terahertz radiation has proven particularly tricky to use.

New Faraday Cages Can Be Switched Off and On

Built out of a novel material called MXene, these cages could block and allow signals as desired

Advanced new Faraday cages—the metal mesh enclosures that can block wireless signals—can also be switched on and off for reversible protection against noise, a new study finds.

In addition, these new shields can be easily fabricated through a technique akin to spray-painting, which could help them find use in electronics, researchers say.

Similarly to how window blinds can help adjust how much visible light enters a room, engineers want dynamic control over the electromagnetic waves used in wireless communications. This ability would let devices receive and transmit signals when desired but also protect them against electromagnetic interference, such as static and jamming, and help them avoid being spied on.

Adhesive staking of DIP component on a circuit board using Master Bond EP17HTDA-1.

The main use for adhesive staking is to provide extra mechanical support for electronic components and other parts that may be damaged due to vibration, shock, or handling.
