Surface Currents on a Sphere
Surface currents on a sphere of radius ka=6.283. Excitation is from a vertically-polarized plane wave incident from the right. Frequency varies from 10 MHz to 1,000 MHz.
Surface Currents on a Thin Plate
Surface currents on a thin plate 38cm x 38cm. Excitation is from a vertically-polarized plane wave incident broadside to the plate. Frequency varies from 50 MHz to 3,000 MHz.
Electric Fields Inside a Circular Cavity of Radius
Electric Fields inside a circular cavity of radius = 30cm. Excitation is from a 1 V/m source in a small aperture at the left of the figure. Frequency varies from 20 MHz to 1,000 MHz.
Front-Fed Log Periodic Antenna
