MODELING STUDIES. SUBSURFACE PROPAGATION
Abstract
This rept. includes: FIELDS FROM A BURIED HORIZONTAL DIPOLE IN A FLAT EARTH - FLAT IONOSPHERE SYSTEM, by A. F. Gangi. Mar 62 (Rept. no. SGC TM 1-10) The theory of electromagnetic wave propagation in a flat earth-ionosphere system from abovesurface and subsrface antennas is discussed. Calculated results obtained from a digital computer are compared with experimental results obtained from a scaled model of the earthionosphere system. The experimental results were obtained from two scale models, one a flat earth-ionosphere model and the other a spherical earth-ionosphere model. Scale factors of the order of one million were used in the propagation models. The properties of subsurface antennas and antenna arrays were investigated using modeling techniques. The experimental results were compared with theoretical results. Criteria for the design of subsurface antenna arrays were obtained. A description of the instrumentation used in the antenna characteristics measurements and in the propagation models is given. Recommendations for future research and developments are also presented.
