| 摘要: |
| 光子晶体在微波毫米波领域已经有了广泛的应用，适合于微波集成电路结构的光子晶体结构将具有很大的应用前景。在微带介质层上周期加载矩形金属贴片，可以获得平面微波光子晶体，并且在特定频段内禁止表面波传播。利用格林函数和矩量法对这种平面微波光子晶体结构进行了计算，通过求解特征方程，得到在这种微带结构中表面波的传播常数，并通过参数设计得到所需要的表面波带隙。这种结构对于微波集成电路和相控阵天线具有很大的应用价值。 |

| Abstract: |
| Photonic crystals have been extensively used in microwave and millimeter wave application,and that kind of photonic crystal whose structure is integrated into microstrip circuits have a good future.Microstrip structure periodically loaded with rectangular metal patches can be designed to be an excellent photonic crystal with a planar topology.Surface wave in certain frequency band will not be permitted to propagate.In this paper,Green's function plus method of moments is introduced to analyze this kind of photonic crystal.The propagation constant of surface wave for this microstrip structure is obtained by solving the characteristic equation.Proper parameters are chosen to get expected surface wave bandgap.This microstrip structure is valuable to microwave circuits and phased array antennas. |
