## Homework Statement

Two lossy homogeneous dielectric media with dielectric constans ϵrl = 2, ϵr2 = 3 and conductivities a1= 15 (mS), σ2 = 10 (ms) are in contact at the z = 0 plane. in the Z>0 region a uniform electric field E1 = 20i - 50k

exists (i and k being unit vectors in the x and z directions)..

Ok so my question is this in one of the parts of the question it asks for the surface charge density on the interface, however since both media are dielectric shouldn't the surface charge density be 0 according to the boundary conditions of electric fields

## Homework Equations

D

_{1n}- D

_{2n}= P

_{s}(surface charge density)

where D

_{1n}- D

_{2n}are the normal components of the electric flux densities of media 1 and 2 respectively

## The Attempt at a Solution

the way I see it, and according to what is stated in the textbook Ps should be 0, however the solution manual states differently
