# Absorption loss of metal shielding

A plane metal shield offers an absorption loss of 30 dB at a frequency of

10 kHz to normally incident radiated emission.

(a) Determine the absorption loss at 10 kHz in a shield of five times the

thickness.

(b) Determine the absorption loss at 20 kHz in a shield of half the

original thickness.

#### Solution Preview

Dear Student,

Absorption loss of shielding in a metal is given by,

A= (3.338e-3)*t*sqrt(u*f*G)

where,

A is absorption loss in db

t is thickness in mils

G is the relative ...
