Abstract

In the case of the artificial circular dielectric resonator which is encapsulated in a circular waveguide, the resonance characteristic is determined not only by a resonator thickness but also by a novel anisotropic permittivity value and a radius of a circular waveguide. In this paper, the relationship of its parameters is calculated and analyzed. The calculation is done by using the mathematical formulation which is derived from Maxwell's equations with proper boundary condition. The research is focused on the influence of the resonator thickness to the TM resonance characteristics of artificial circular dielectric resonator. The results show, the ability of novel anisotropic in p direction increase due to a radius of a circular waveguide enhancement for TM0, wave mode, whilst, the ability increase due to a radius of a circular waveguide reduction for TMU wave mode. A novel permittivity in p direction is effective reduce the resonant frequencies for thin resonator thickness.

材料厚度对各向异性人工圆形介质谐振器谐振特性的影响

对于封装在圆波导中的人工圆形介质谐振腔，谐振特性不仅取决于谐振腔的厚度，还取决于一种新的各向异性介电常数值和圆波导的半径。本文对其各参数之间的关系进行了计算和分析。利用麦克斯韦方程组的数学公式，在适当的边界条件下进行计算。重点研究了谐振腔厚度对人工圆形介质谐振腔TM谐振特性的影响。结果表明，对于TM0波模式，圆波导半径的增大增加了p方向新各向异性的能力，而对于TMU波模式，圆波导半径的减小增加了新各向异性的能力。在较薄的谐振腔厚度下，新的p方向介电常数可以有效地降低谐振频率。
