Potential Coefficients for Ground Return Circuits

= Airau, as in Carson's work on Z« and in mine on Zn at high frequencies 1 ' 2 fe'' = Vl + *'(« - 1)/2cX 0, / --> °°, e --> °o or a --» Ordinarily 4(JI/ + iN) will not be an important correction to 2 l o g p " / p ' ; but if the frequency is high and h or z is small it can be a worthwhile correction. For example, if a .02535 inch wire be thrown out on the ground to be a 2 mc antenna and we assume that
