Defining Spherical Modes Data from File

Import spherical modes data from a TICRA .sph file or import from a .sph file exported by CADFEKO, to create a spherical modes data definition. Use the spherical modes data definition when defining an equivalent source or receiving antenna.

1. On the Construct tab, in the Define group, click the  Field/current data icon. From the drop-down list select  Import spherical modes data from file.

2. In the TICRA (*.sph) file field, browse to the file location.
3. Specify the data block to be used:
   • To select data from a multi-frequency .sph file, select the Use all data blocks. The data is interpolated for use at the operating frequency.
   • To select data from a specific frequency in the .sph file, clear the Use all data blocks and enter the number of the relevant data block.
4. In the Label field, specify a unique label for the spherical modes data.
5. Click Create to define the spherical modes data and to close the dialog.
