External Electric Field

EXTERNAL-FIELD [real real real]

Applies an external electric-field vector. The three values are the X, Y, and Z components of the field in MV/cm. In the absence of EXFLD-FREQ, the applied field is static.

For example, the following applies a static field of 1.0 MV/cm along the positive Z-axis:

external-field  0.0  0.0  1.0

EXFLD-FREQ [real]

Sets the frequency of an oscillating external field in GHz. When this keyword is present, the vector specified by EXTERNAL-FIELD is the field amplitude and is modulated sinusoidally at the requested frequency.

For example, the following applies a field along the positive Z-axis with an amplitude of 1.0 MV/cm and a frequency of 0.1 GHz:

external-field  0.0  0.0  1.0
exfld-freq      0.1
