Microwave photonic crystals with electrically controlled characteristics

The results of investigations of waveguide and microstrip photonic crystals with electrically controlled characteristics have been presented. The designs of photonic crystals with electrically controlled characteristics based on microstrip lines and waveguides with dielectric filling, with resonant diaphragms and frame elements, which can be used both for the creation of microwave switches, selectors, signal modulators, and high-sensitivity systems for measuring materials parameters at microwaves have been proposed.
