Understanding which microwave absorber to use is very important for engineers today. Alot of times, people get confused between narrowband, surface wave, and low frequency materials. Choosing the wrong one can lead to failed testing and alot of wasted time on the bench.
Designing a PCB for modern wireless devices means you have to deal with alot of EMI. Board level shields are the most effective way to stop cross-talk at the source. If you dont plan for your PCB shield early, you might face expensive redesigns when you hit the compliance lab.
