According to the method of the image, an infinite conducting surface can be replaced by an image change with equal distance without affecting electric or voltage distribution.
Analysis:
Note:
Boundary Condition
\(1.\;\left| {{{\vec E}_t}_1 = \left| {{{\vec E}_t}_2} \right|} \right|\)
\(2.\;\left| {{D_n}_1} \right| - \left| {{D_n}_2} \right| = {\rho _s}\)
\(3.\;\left| {{{\vec H}_t}_1} \right| - \left| {{H_{{t_2}}}} \right| = {{\hat q}_{n12}} \times \hat k\)
\(4.\;\left| {{B_N}_1} \right| = \left| {{B_N}_2} \right|\)
ρs = surface charge density
k̂ = surface current density
