电磁波在损耗媒质界面反射折射基本规律的理论研究

It is found that the ordinary boundary conditions of harmonic electromagetic fields at interface of lossy media may not be satisfied simultaneously, which is due to that the different damping terms between the two media may lead the flux at Gauss surface and circumfluence along close loop of electromagetic fields near interface to be no longer harmonic. Considering effects of media loss on equations of harmonic electromagnetic fields and their boundary coditions, we obtain new relations of amplitude and direction among the incident, reflected and refracted waves. It is shown that both imaginary part of propagation constant and wave resistivity may alter direction of the refraction wave, then alter the coefficients of reflection and refraction. These results offer the possible experiment way to test in some degree the equations of harmonic electromagnetic fields given in the text, and the feasible way to adjust direction of wave, coefficients of reflection and refraction, and so on.
