The Single-Gap Hollow Spherical Dipole in Non-Conducting Media
Carl E. Baum · Defense Technical Information Center (DTIC) · 1993
This note considers the response of a hollow spherical dipole in non- conducting media. This sensor is a sphere with a slot around the equator which is uniformly resistively loaded. The current through the resistive load across the slot is proportional to the time rate of change of the displacement vector for low frequencies. The response characteristics of such a device at high frequencies are calculated using expansions in spherical wave functions. These calculations include the dependence of the sensor response on both frequency and the direction of wave incidence....Hollow spherical dipole, Non-conducting media.
