Given a plane electromagnetic wave of frequency f = 100 mhz propa- gating in wood for which material parameters are: fls = 1; er = 3; 0 = 10-s/m. (a) show that wood "qualifies" as a low-loss medium; (b) determine the attenuation coefficient a; (c) determine the distance over which the wave is attenuated by 1 db; (d) determine the phase constant b; (e) determine the propagation velocity vp; (f) determine the intrinsic impedance ne
