AN AGAR AGAR CHAMBER FOR THE STUDY OF ELECTROMAGNETIC WAVES IN AN INHOMOGENEOUS MEDIUM.
Abstract
A medium for the propagation of electromagnetic waves whose dielectric constant or loss tangent has a prescribed profile was fabricated by using a large quantity of agar agar in simulation chambers. The dielectric constant of the agar agar could be changed continuously by means of a controlled diffusion of ethyl alcohol. The loss tangent of the same medium could be changed continuously by means of a controlled diffusion of sodium chloride. This is the first of a series of reports. It is concerned with the design and characteristics of the simulation chamber. Measured results obtained with the chamber are described in later reports. Topics to be considered include the properties of agar agar in a wide frequency spectrum, the diffusion constant of NaCl in agar agar, the diffusion profiles, a re-examination of the principle of simulation, the construction of various types of probes and simulation chambers.
