You are working on an electromagnetic method for measuring the speed at which blood flows through arteries and veins inside the human body. Blood contains both positive and negative ions flowing together in the same direction. If those currents are exposed to a perpendicular magnetic field, they will be pushed in opposite directions, causing a charge separation between the two...

Regulations require that licensed radio stations have limits on their broadcast power so as to avoid interference with signals from distant stations. You are in charge of checking compliance with the law. At a distance of 35 km from a radio station that broadcasts from a single vertical electric dipole antenna at a frequency of 1090 kHz, the intensity of...

Figure 1.2 Figure 1.2 shows a Wilkinson coupler, with conducting strip shown hatched, implemented in microstrip designed to split power equally between two matched 502 outputs. Briefly explain the following features: 2%) why the electrical length of the two output arms of the coupler is designed to be a quarter wavelength; (i) (ii why the characteristic impedance of each arm...
