摘要
研究了Ku波段光子晶体加载曲折波导慢波结构的色散特性和耦合阻抗。用电磁仿真软件CST MWS进行了仿真,讨论了慢波结构外光子晶体对慢波通道内电磁波的选择通过性。对具有相同结构尺寸慢波结构的研究结果表明:光子晶体加载慢波结构的色散比传统曲折波导慢波结构的色散低;和传统曲折波导慢波结构相比,光子晶体加载曲折波导慢波结构的耦合阻抗略高。
This paper studies the dispersion characteristics and the Pierce interaction impedance of Ku-band folded-waveguide(FW) slow-wave structure(SWS) Shielded by Photonic crystals(PhC).The structure is simulated with the code CST MWS,and the selectivity of PhC to electromagnetic waves in the SWS is discussed.The results reveal that the dispersion of the FW SWS with PhC is smaller than that without PhC,while its Pierce interaction impedance is slightly higher.
