Problem 4. (25 points) Electromagnetic plane waves are used to penetrate an earthen wall to investigate the suspicion of a hidden chamber behind it. This suspicion is well-founded, as shown in the figure below: 2007 $ Cliparts.com Cartoon money bags free cliparts saya fik 5 m Three frequencies are available from your equipment: 100 Hz 10 MHZ 1 THz = 102 Hz The materials properties of the dirt in the wall are: L = 1 Ey = 3.4 11 03.0 x 10-3 Am a) Calculate the Loss tangent at each of the 3 frequencies b) Calculate the attenuation coefficient at each of the 3 frequencies c) Quantitatively demonstrate whether any of these frequencies can penetrate the wall into the hidden chamber while retaining exp of the initial signal strength.
