Describe electromagnetic shielding. A uniform wave propagating in free space strikes a lossy medium with a dielectric constant of 20 and conductivity of 0.8 mS/m. The frequency of the wave polarized in the X-direction is 200 kHz. Determine the angular frequency, propagation constant, intrinsic impedance, and phase velocity. Outline three sources of electromagnetic radiations. A conductor of length 10 cm carries a current of 2A in a vertical direction. A point P is placed 1 m away from the conductor in the X-direction. Stretch the arrangement; determine the angle between the vertical axis and point P; determine magnetic field at point P using Biot-Savart law.
