摘要 给出一种新型横电磁波传输室—圆锥形横电磁波传输室 ,并在球坐标系下采用时域有限差分 ( FDTD)法对其场分布进行计算 ,分析了高阶模的影响 ,确定了传输室的上限工作频率范围。分析和计算结果表明 ,圆锥形横电磁波传输室的电场极化方向可任意改变 ,上限工作频率可达4 GHz。 A kind of conical transverse electromagnetic cell is proposed in this paper. The field distribution, field uniformity and the upper operating frequency have been analyzed using FDTD method in the spherical coordinate .The upper operating frequency of the cell can be raised to 4GHz. The results are useful for the design and application of new TEM cell.
