The integrated form of the Brody effect

We have considered the simplest model of the Brody effect: a circular inhomogeneity into a conducting medium of infinite extent energized by a source sink pair near the disk. To correlate with the reciprocal field equations, the Brody effect has been calculated in its integrated form by the Gabor-Nelson method (1954). In these conditions, our results do not depend upon any singular position on the closed contour; they are also invariable with respect to grounding the inhomogeneity and/or shifting the inhomogeneity centre from that of the compartment around it. Contrariwise, characterizing the Brody effect by an enhancement factor of local potential values is sensitive to the above factors and so, may become confusing because inducing the belief that the effect due to an inhomogeneity intrinsically depends upon removing the point from which it is viewed.
