How to Calculate the Electric Field Intensity E (V/m) at the center of Medium-2, if Medium-2 is in Medium-1 at distance of d1 as shown in attachment?
Given:
Operating Frequency, f (GHz)
RF Power, P (W)
Horn Antenna Gain, G (dBi)
Medium Characteristics, Permittivity & Permeability etc.
Distance to calculate the E (V/m)
Note: Medium is in near Field of Horn Radiation Pattern.
