Abstract :
Radiation in an unbounded anisotropic medium is treated analytically by studying the dyadic Green´s function of the problem, initially expressed as a triple Fourier integral which is next reduced to a double one. Under certain conditions, the existence of incoming waves is verified. It is also found that exponentially decaying waves are possible in such media. Finally, the existence of branch points in the remaining integrand function is investigated, and appropriate branch cuts are proposed
