WebOct 8, 2014 · That's how EM absorption works. The receiving antenna has launched a wave which "sucks in" energy from the incoming wave. The reception of EM waves is a wave-cancellation process. This wave-cancellation explains how light-absorption works; how atoms absorb photons, how objects cast shadows, and how antennas receive radio … WebDec 8, 2016 · It can be made inductive by tuning it below resonance. This can be done by physically adding some inductance to the element in the form of a coil, or more commonly by making it longer than the resonant length. Generally it is …
