The Use of Absorbers in Electronics

The trending small size of electronic devices coupled with higher data speeds, there is a merging of the increasing physical closeness among components and the shrinking wavelengths associated with higher speeds. As wavelengths shrink, they approach the physical dimensions of components and devices which results in increased “antenna effect” of noise. So, it is becoming increasingly critical to prevent coupling of noise to these objects that can radiate and/or to reduce the coupled field levels, since it is becoming more difficult to shield products in a cost efficient manner at higher frequencies.
