A uniform plane wave with E i (z) = a x E i0 e -j 0Z in air propagates normally through a thin copper sheet of thickness d, as shown in below Fig. Neglecting multiple reflections within the copper sheets, find
a) E 2 + , H 2 +
b) E 2 - , H 2 -
c) E 30 , H 30
d) ( P av ) 3 / ( P av ) i
Calculate ( P av ) 3 / ( P av ) i for a thickness d that equals one skin depth at 10 (MHz). (Note that this pertains to the shielding effectiveness of the thin copper sheet.)
