Consider two z-directed hertzian dipoles spaced a distance d apart along the x-axis. the right dipole is driven at a magnitude and phase difference ae with respect to the left. sketch the normalized radiation pattern (or use matlab! ) in the x-y planes for the following cases: (a) d-ad 1 (b)d-/2. ad-1 (c) d-2, ad in which direction() is the gain maximum for each case? partial solution: (a) maxima: 60°, 120. minima: 0, 90", 180 (b) maxima: 109.5. minima: 48.2 (c) maxima: 29.0, 68.0°,97.2, 128.7 minima: 51.3, 82.s". 112, 151

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
