Microwave heating has the advantages of instantaneous,controllable and high-efficiency,and it has been widely used in the preparation of novel materials,nuclear industry,drying of precious Chinese herb,chemical reaction catalysis,food heating,etc.The microwave reaction chamber is the key equipment of the microwave heating system.A more reasonable design of microwave reaction chamber has a decisive impact on the efficiency,uniformity,and controllability of microwave heating.Based on the Bragg scattering characteristics of photonic crystals to electromagnetic waves,in this work,we introduced the photonic crystals into the traditional cylindrical microwave reaction chamber and designed a novel cylindrical photonic crystal microwave reaction chamber.On this basis,simulation studies have been conducted on the influence of photonic crystals to heating efficiency and uniformity.The results show that,comparing with the traditional cylindrical microwave reaction chamber,the cylindrical photonic crystal microwave reaction chamber has higher heating efficiency and uniformity.
