1. Modeling Insert design

Create a model

Assign dimension (for example 10.7mm by 4.3mm)

Assign material (to be vacuum, which is same as default)

2. Assign boundary & excitation Assign boundary (to be perfect E, which is same as default)

Assign excitation (both ports to be wave ports)

Everything use default, assign port 2 using same method.

3. Analysis

Change solution frequency to be center frequency of your frequency band or something higher, the higher the solution frequency is, the longer time the solver will take.

(for example, 30GHz here)

Add frequency sweep

Change the start and stop frequency

Validate the whole structure

Analysis

(this will take some time)

4. Results Plot the S-parameters

We want to see the reflection & transmission (S11 & S21)

New report (A clear cutoff frequency at around 14 GHz)

Plot the E field

Transparent the waveguide to see more clearly

Animate the field
