Resumen

It is demonstrated that Friis equation can be derived from a perturbed wave equation of electric field. When the wave equation is brought to a territory of Green function in conjunction to Fourier transform into the wave vector space, the Friis equations is obtained in a straightforward manner. Indeed, some conditions emerge. Under this scenario, the singularities are identified and are correlated to aspects of free space propagation. Alternative scenarios that might be also interpreted as an approximated transmission equation, are also presented. This would corroborate the idea that might exist a family of equations instead a single one.
