Application of the reciprocity theorem to complex propagation problems

Based on the reciprocity theorem, the present report has developed a propagation algorithm that can take account of the effects of changing ground properties, topography and the presence of buildings. By segmenting the problem at boundaries where significant changes take place, the approach can obta...

Description
Summary:Based on the reciprocity theorem, the present report has developed a propagation algorithm that can take account of the effects of changing ground properties, topography and the presence of buildings. By segmenting the problem at boundaries where significant changes take place, the approach can obtain accurate results from no more than geometric optics dipole fields. Since a geometric optics solution is readily derived for situations where the refractive index is continuously varying, the technique can easily incorporate the propagation effects of the atmosphere and/or semi-transparent objects.
