Quasi-Static Magnetic Field Penetration into a Hemispherical Indentation in an Infinite Conducting Plane.

摘要

The problem of the penetration of a quasi-static magnetic field into a hemispherical indentation in an infinite conducting plane is formulated as an integral equation and solved numerically to a high degree of accuracy. The results are directly applicable to the study of a large class of aircraft antennas, such as the marker beacon antenna. The value of the magnetic potential inside the cavity, the induced magnetic dipole moment, and the magnetic flux passing through a receiving loop antenna erected in the cavity are calculated.
