A 3×3 board with 9 squares on the front and 9 squares on the back is to be colored with 4 colors. The squares can be red, green, blue or yellow. For example, one side might be a red and green checkerboard pattern and the other side might be a blue and yellow checkerboard pattern. How many different colorings are possible? Use the symmetry group of the square, D4, which has order 8. This is an abstract algebra homework.

A radio antenna works by having the electromagnetic radio wave induce oscillations in the electrons in the antenna. one peculiarity of radio antennas that often confuses people is that, while the bigger the antenna is the more power it can draw, the optimum length for a radio antenna is 1/4 the wavelength of the radio wave. What does this suggest about the mechanics of a radio antenna?

A radio transmitter is connected to an antenna having an impedance 80 + j40 ohm with a 50 ohmcoaxial cable having a length of 2.0 m. The impedance of the transmitter is 50 ohm . The phase velocity of the signal propagation in the coaxial cable is 2.0*108 m/s, and the frequency of the sinusoidal signal is 800 MHz. Find the following quantities: a) The propagation constant of the signal in the cable. b) The reflection coefficient at the antenna....

Car mirrors are uncoated on the front surface and silvered on the back surface. When the mirror is properly adjusted, light from behind reflects from the silvered surface into the driver’s eyes. Good. But this is not so good at nighttime with the glare of headlights behind. This problem is solved by the wedge shape of the mirror (see the sketch). When the mirror is tilted slightly upward to the “nighttime” position, glare is directed upward toward the ceiling, away...

The voltage measured by a certain antenna is 5V for every V/m of the incident electric field at 100 MHz. What voltage (dBìV) at the antenna terminals corresponds to the FCC Class B limit at 100 MHz? At this antenna voltage, what voltage is measured by a spectrum analyzer when connected to the antenna by 200 ft of coaxial cable with 4.5 dB/100 ft of loss at 100 MHz. [Answer: 57.48 dBìV, 48.48 dBìV]

Problem 1. The emitting antenna of a 100 kW radio station radiates equally in all directions. What are the magnitudes Emax and Bmax (a) 100 m from the antenna and (b) 50 km from the antenna? (c) For these two distances from the antenna, calculate the maximum potential difference caused between the ends of a receiving antenna that is 1.0 m long, assuming the antenna is aligned perfectly with the electric field of the radio wave

A dish antenna having a diameter of 22.0 m receives (at normal incidence) a radio signal from a distant source. The radio signal is a continuous sinusoidal wave with amplitude Emax = 0.800 µV/m. Assume the antenna absorbs all the radiation that falls on the dish. A dish antenna on top of a tall tower extending above the trees. The dish points upward and to the left. Three parallel wavy arrows come come downward and to the right toward the...
