含广义交叉耦合的N个谐振器滤波器,即含源-负载交叉耦合的滤波器能产生N个传输零点,通过给出这种滤波器的等效网络模型和传输函数,设计了两种新颖六边形结构的含源-负载交叉耦合的微带滤波器,一种为对称结构,一种为非对称结构。
Firstly,this paper constructures the spherical hexagonal grid based on icosahedron using Snyder equal-area projection.
利用二十面体施奈德等积多面体投影构建了球面多分辨率六边形层次网格;通过边界四元组将六边形单元分解到四元三角形及其子单元中处理;利用改进的四元三角网编码方案建立了网格的数字空间、单元层次编码模型和不同实体在球面上的表达方法。
This paper concludes that if the structure of mesh lattice units is formed in the shape of regular hexagon, the data precision can be raised under the condition of equal area and equal amount of data and, the data amount can be lessened under the condition of keeping equal precision, thus loweri.
