PHOTONIC CRYSTALS - A NEW QUASI-OPTICAL COMPONENT FOR HIGH-POWER MICROWAVES

The interaction of a high-power microwave beam with a face-centered-cu bic photonic Crystal is studied, A Sinus-6 high-power relativistic rep etitively pulsed electron beam accelerator was used to drive a slow wa ve structure in vacuum to generate 450 MW at 9.65 GHz, It is shown tha t the photonic crystal, comprised of a periodic arrangement of air hol es in a dielectric host, is capable of performing as a quasi-optical r eflector similar to a metal. The crystals can be designed to operate a s efficient frequency-selective reflectors over narrow frequency range s, We propose that photonic crystals can have many applications in hig h-power microwave research.
