Abstract [en]

In this report, the Fast Fourier Transform is described briefly. An implementation, inthe form of the Fortran code four1, is tested to verify the accuracy. A two-ray modelfor wave propagation above a flat earth is discussed. The case with AM modulation isimplemented in a Mathematica script. Calculations of the surface current density, withthe program NERO, are made to test the accuracy. The transient scattering from a PECcylinder is studied by means of the code run_nero that runs NERO repeatedly. From aspectrum calculated in this way, the impulse response is obtained by Fourier inversion.
