Cavity with one side permeable -------Zhonghai Liu
Hertz Potential • For a rectangular cavity, it’s convient to single out one particular direction, say ,and choose the Hertz potentials as: • Then: • Correspondingly:
Cavity with one side permeable • For conducting surface: • For permeable surface: • Without loss of generality, assume the permeable side is on z=c
