Problem 1 (30 pts) A plane wave in a lossy, non-magnetic medium is propagating in the +z direction, at an operating frequency of ƒ =100MHz with the following electric field intensity expression: E(2,1)=0.765e cos(at-Bz+0) The field has the following waveform with respect to z at t=0. E❘ (volts) 0.712 0.010801 z (m) 2.094 4.188 a) Evaluate the value of ẞ in rad/m. b) Evaluate in degrees. c) Calculate the skin depth. d) Evaluate the intrinsic impedance of the medium at the given operating frequency. e) Evaluate the magnetic field intensity. f) Evaluate the time-average power per unit area at z=1m.
