Derek, In my previous E-mail, for item 4 (4*|Zs||Zw|)/((|Zs|+|Zw|)^2) is the fraction of impinging *power* that reflects off the air-to-shield interface of the wire mesh. The reflected electric field (E-field) or magnetic field (H-field) will be the square root of this times the impinging E-field or H-field, i.e. (2*(|Zs||Zw|)^1/2)/(|Zs|+|Zw|) times the impinging field.
