摘要
Ideal or near ideal filter for reflecting or transmitting electromagnetic waves having wavelength range of approximately 100 nm to 10 cm are disclosed. These filters combine a dielectric multilayer structure with a resonant waveguide grating and they are valid for both TE and TM polarized waves. High efficiency, arbitrarily narrow band, polarized, filters with low sidebands over extended wavelength ranges can be obtained.
