R320 Hollow Rectangular Waveguide

1. Example description

In the following example a standard R320 hollow rectangular waveguide is simulated, see Fig. 1. The cross section of dimensions 7.112 mm and 3.556 mm.

2. TLM model

The waveguiding structure, excitation-type and simulation setup are given in the TLM model files and I3D.r320.

In the first file the structure is excited with a Gaussian signal. The excitation is modelled by a vertically polarized electric field at one port of the waveguide as shown in Fig. 1. Absorbing boundary conditions are used at the boundaries of the simulation domain.

3. Simulation Results

3.1 Electromagnetic Field Visualization

As simulation result we display a snapshot of the field distribution inside the waveguide, Fig. 2
