Resonant wave filter |
摘要 |
A compact resonant wave filter capable of selectively propagating an electromagnetic wave of a prescribed frequency with excellent band-pass wave filter characteristics comprises a TM mode resonator disposed perpendicularly to the direction of propagation of electromagnetic wave energy, a pair of TEM mode resonators disposed one on either side or said TM mode resonator in the direction of propagation of electromagnetic wave energy, and a pair of cutoff waveguides disposed one between said TEM mode resonator and each of said TM mode resonators to couple said TEM mode resonator with said TM mode resonators in evanescent mode. |
