Calculating the polarization allows me to determine the contribution to the potential from the polarization surface charge density and polarization volume charge density.
I think your incorrect about the need for a continuous potential. The parallel E component and the perpendicular D...
I've been working on this for a little while now (in CGS units), and am not really sure where I've gone wrong at in calculating the potential, so I've come here! Here is the problem:
What is the potential caused by placing a point charge Q at the center of a dielectric sphere (\epsilon2)...
It does have two simple poles at I am and -im, but if k is positive the contour will be closed upwards (the contour's edges run along with x-axis, then form a half circle in the upper plane; taking the radius of the half circle to infinity, we find that this contour is exactly equal to the...
