A MFIE-based prediction for UHF vertically-polarized wave propagation over irregular terrains

A MFIE-based technique is applied an the propagation prediction of vertically polarized radio waves. The terrain profile is assumed smooth, such that backscattering is neglected and a forward scheme applied to obtain the induced surface currents. The MFIE is compared against the EFIE for several case studies. It is demonstrated that, under the present assumptions, the MFIE provides the same accuracy with a smaller number of basis functions, specially where the line-of-sight is obstructed.
