Abstract :
An ideal reflection (band-stop) filter with high efficiency and symmetrical shape under TM normal plane-wave excitation is theoretically demonstrated using a periodic dielectric grating. It is shown that the resonance frequency and the bandwidth of the filter can be controlled by the angle of incidence and the grating modulation, respectively. Finally, a double-band reflection filter under TE normal plane-wave excitation is obtained in a structure containing two gratings with different grating periods.
