Suppression of Microwave Leakage by Photonic Crystals

The idea of using photonic crystal band gap to suppress the leakage of industrial microwave equipment is proposed, and its feasibility is proved by simulation experiments. The band structure of photonic crystal is adjusted to control the electromagnetic wave. Compared with the traditional microwave suppressor, this method has better suppression performance and lower manufacturing cost, and its application range is wider than the traditional suppressor.
