Two identical short dipole antennas are driven in phase with each other with equal strength andemit readiation at a wavelength of = 0.1 meters.One antenna is oriented in the y-direction and is located at (x,y,z) = (0,0,0). The other antennais oriented in the z-direction and is located at (x,y,z) = (d,0,0) where d > 0.What is the smallest value of d for which the radiated far-field at a point (x.y,z) = (X, ,0, 0), x,>>d, and A, is circularly polarized?What happens to the polarization if d is now doubled?

A loose definition of polarization is the direction in which electromagnetic fields emanate from an…

Mammography is an x-ray imaging procedure for breast cancer diagnosis and screening. Assume that 20ke V x-ray is used in mammography. Also assume that the breast of a patient is 6 cm in thickness (soft tissue), and the propagation speed of x-ray photons in soft tissue is about the same as in vacuum. How long will it take for x- ray photons to travel through the breast?

A quarter-wave monopole radio antenna (also called a Marconi antenna) consists of a long conductor of one quarter the length of the transmitted wavelength. The lower end of the antenna is connected to a conducting ground plane (often simply the Earth) which reflects the transmitted signal, creating an effective antenna length of a half wavelength. (a) What must be the height of the antenna (in m) for a radio station broadcasting at 569 kHz? (b) What must be the height of the antenna (in m) for radio stations broadcasting at 1,750 kHz?
