A vector model of wave propagation through an interface of dissipative media

详细

The possibility of solution of the problem of wave propagation through an interface of two dissipative media with the help of a trigonometric vector model is shown. Two invariants independent of the dissipation of these media are revealed: (i) the sum of projections of vectors of reflected and transmitted waves onto the polar axis, which is equal to the projection of the vector of the incident wave onto the same axis, and (ii) the sum of projections of vectors of these waves onto the normal to the polar axis, which is equal to zero.
