Microwave component
 
A three-port microwave component filled with metamaterial is simulated by using GEMS. One port serves as an excitation, and other two ports are the outputs. GEMS is used to simulate the S-parameters and field distribution inside the component.
 
The basic design procedure in the simulation:
Draw a box and generate a shell using the “Shelling” option
Assign it to be PEC material
Add three ports
Import the metamaterial into the box and assign it to be lossy material
Draw three rectangles at the three ports and define one of them as the excitation port and other two as the output ports
Use the TE10 as the excitation mode
Set the domain size and boundary
Generate the adaptive mesh
Specify the convergence criterion
Simulate the project using a single PC or cluster
The basic settings in the simulation:

Description
Boundary PML truncates three sides that touch the three ports; PEC truncates other three sides PEC boundary is used due to the closed system.

Mesh Non-uniform and conformal mesh Adaptive mesh
Output S-parameters, and time domain field distribution inside the component It will take long time to get the convergence result due to the high-Q property
