We’ve always been fascinated by things that perform complex electronic functions merely by virtue of their shapes. Waveguides come to mind, but so do active elements like filters made from nothing but ...

The field of filtering antennas integrates antenna design with filtering circuits, thereby achieving simultaneous radiation and frequency selectivity. These systems are engineered to transmit or ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...
