Floquet Port: Modes Calculator
- In the Floquet
Port: Modes tab, if you select the Modes calculator
button, the Mode Table Calculator window displays.
Enter the following fields:
- Number of modes - you can trim this value later, as you learn which modes are needed and which are not.
- Frequency - if the problem setup contains one or more frequency sweeps, usually you will set this value to the highest frequency.
- Scan Angles -enter the values and select units for Phi and Theta, including Start, Stop, and Step size. The Mode Table Calculator calculates a set of Floquet modes on the basis of all the angles defined.
These inputs constitute the information required to create a set of recommended modes for the Floquet port. The inputs are used by the mode selection algorithm but do not affect the problem setup.
- Click OK to leave the Mode Table Calculator and to compute the recommended list of modes.
The new modes table appears on the Modes Setup tab of the Floquet Port properties/setup window. The attenuation associated with a listed mode represents the minimum (or worst case) for that mode over the range of scan angles.
