A sirloin steak (e'r = 52.4, µr = 1, tan dc = 0.33) is to be heated in a microwave oven operating at 2.45 Ghz.
(a) Determine the uniform plane wave penetration depth.
(b) Determine the complex impedance of the material.
(c) If the plane wave is exposed to a surface that measures 10 cm x 10 cm, find the electric field amplitude at the surface of the steak that will cause an average of 100 W of power to enter the material.
