Active isotropic slabs: Conditions for amplified reflection

Mostrar todas las versiones(2)

We analyse in detail the necessary conditions to obtain amplified reflection (AR) in isotropic interfaces when a plane wave propagates from a transparent medium towards an active one. First, we demonstrate analytically that AR is not possible if a single interface is involved. Then, we study the con...
