2 1. An EM wave is incident onto a perfect conductor. Which of the following statements are true? ABD A) The electric field amplitude at the surface of the conductor must be zero. B) A standing wave exists in the region of space in front of the conductor. C) The space between the adjacent maxima of the standing wave is equal to the wavelength of the incident wave. D) At certain points the standing wave amplitude is always zero. E) All of the wave is transmitted into the conductor. 2. The E-field of an electromagnetic wave travelling in vacuum is represented by the equation below. ܧሺݕ,ݖ, ݐሻ ൌ ൫4.33ܽ ൅2 .5ܽ ൯ܴ݁ൣ݁ݔ݌൫݆ሺ2ߨ݂ݐ ൅ 5.71 ൈ 10 ݕ െ 9.89 ൈ 10 ݖሻ൯൧ V/m, where f is the frequency of the wave. Which of the following statements are true? CE A) The wavelength is 1.5 ൈ 10 ି଺ ݉ . B) The wavelength cannot be determined from conditions given. C) The wave is traveling in the y-z plane. D) The magnetic field may be located in the y-z plane. E) The wave is linearly polarized. 3. A uniform plane wave, propagating in the z direction, is normally incident on a lossless anisotropic material, with a thickness of d . The dielectric constant encountered by waves polarized along y differs from that seen by waves polarized along x . As a result, the phase of the x-polarized wave will lag that of the y-polarized wave by 10° for every 0.2 mm propagation distance along the z-direction. Which of the following statements are true?
