FEASIBILITY OF A THREE-LAYER MODEL FOR USE IN STUDYING THE PROPAGATION OF ELECTROMAGNETIC WAVES,
Abstract
The feasibility of constructing a three-layer model which employs three liquid layers separated by plastic diaphragms has been demonstrated. A small model was constructed to demonstrate the practicability of assembling and maintaining such a liquid model. Experimental results with the model indicate that the device behaves as a lossy parallel plane waveguide. Consequently, the attenuation versus distance follows an exponential curve. Although the small model does not adequately represent the characteristics of the sea-air ionosphere configuration, it does provide a closed model free of reflections for use in the laboratory to demonstrate the relative merits of various antenna configurations. The physical principle of constructing a threelayer model has been determined. It should be possible to build a large model using the same principle of construction which would adequately represent the sea-air-ionosphere configuration related to the propagation of low-frequency electromagnetic waves if the ionosphere can be considered isotropic.
