Dipole Antenna

A half wavelength dipole antenna is employed to validate the GEMS and compare the GEMS results with the analytic result. In GEMS, the default options are used to generate the impedance and far field pattern.  The electric field value is calculated using the following formula

The analytic value of the electric field is 0.82, and the number obtained by using GEMS is 0.81.
