DifferentialMode EMI Calculator
Signal trace segments and their correspoding return paths represent a potential source of radiated emissions. The maximum radiated electric field due to differential currents flowing on traces can be estimated using a closedform expression [1]. The algorithm used to make the calculations below is described in [2].
 Assumptions:

 All dimensions are small compared to the wavelength of interest.
 The net current flowing in one direction (i.e. the commonmode current) is zero.
Note: The signal current is the signal voltage divided by the load impedance.
