HFSS15: Calculating the Relative Permittivity (Epsilon)

Calculating the Relative Permittivity (Epsilon)

The relative permittivity, e_r, is calculated using

(1)

where

• l_eff is the effective wavelength given in meters.

• c is the speed of light.

• f is the frequency of the wave.

Under the Matrix Data tab of the Solution Data dialog box, epsilon is displayed when Gamma is selected as the matrix type.
