Electromagnetic Analysis

Th features of Hertz (the electromagnetic solver) are explained here with some examples.

The S-parameters of microstrip filters can be solved.

In Example 17 of Electromagnetic Analysis, the microstrip filter formed on a dielectric substrate is analyzed.

The filter characteristics (S-parameters) are obtained.

Antenna performance can be solved.

The reflection at the input port, the radiation of electromagnetic waves from the antenna, and the directivity are solved.

The characteristics of microwaves resonators can be solved.

In Example 11 of Electromagnetic Analysis, the TE mode cylindrical dielectric resonator is analyzed.

The resonant frequencies, the Q factors, and the resonant modes are solved.

The time responses of the transient voltage and input current are solved.

In Example 38 of Electromagnetic Analysis, TDR analysis is performed in the time domain.

Output voltage, output current, and the results of TDR are solved.

The functions of the electromagnetic analysis are listed below. For more examples, see [Example List for Electromagnetic Analysis].
