Example12 TE-Mode Dielectric Resonator (2D)

General

• Exercise 11’s TE01δ-mode dielectric resonator is analyzed with axisymmetric modeling.
   

• The resonant frequencies and the electromagnetic field distribution are solved.
   

• Unless specified in the list below, the default conditions will be applied.

Analysis Conditions

* This is the default setting. There are no edge electrodes with this model. Therefore it is irrelevant to select it or not.

xx

The resonant analysis is set up as follows.

Model

The model is basically a section of Exercise 11’s model. DR is a sheet body, a section of dielectric resonator. It is surrounded with rectangular AIR.

The resonator’s hole is represented by another rectangular AIR.

The boolean operation will be performed during the meshing automatically, and the model is recognized as a section of the holed resonator.

The “electric wall” boundary condition is set on the axis of symmetry.

Body Attributes and Materials

* Available from the Material DB

The material property of DR_MAT is set up on the permittivity tab as follows.

Boundary Conditions

The electric wall is set up around the air.

The “electric wall” boundary condition is set on the axis of symmetry.
