Abstract:

A summary of research in electromagnetic phenomena is presented. This review consists of a logically arranged outline of topics with brief summaries and references to the relevant Technical Reports followed by a listing of all Technical Reports and publications resulting from these investigations. The main headings are Antennas Coupled Antennas and Arrays Antennas and Waves in Dielectric, Conducting, or Plasma Media and Miscellaneous Topics. The bulk of this two-volume report is comprised of the results of a rigorous experimental study of monopole and dipole antennas modified to have electrically thick conducting cylinders at their centers. This configuration has many practical applications including antennas on shipboard or spacecraft where the satellite, rocket frame, or ships hull has physical dimensions on the order of a wavelength. Since no exact analytical formulation was available, the experimental design was precisely constructed to give the admittance, impedance, distributions of current and charge, and radiation patterns to a high degree of experimental accuracy. In this, the first volume of the report, a complete description of the experimental design, apparatus, and system of calibration is given along with the measured admittance and impedance results.
