Abstract : The theory of electromagnetic scaling is outlined for media in which the scalar electric conductivity and dielectric permittivity are either constants or functions of position. This theory is applied to the construction of a scale model of the earth-isotropic ionosphere cavity. Construction of the cavity is described. Effects upon field distribution due to eccentricity between the two shells in a perfectly conducting resonator of the earthionosphere dimensions are considered; it is found that correction terms due to eccentricity have a magnitude not greater than approximately one per cent of the unpeturbed fields everywhere except in those regions where the unperturbed fields approach zero.
