Many years ago (prior to the birth of many SEG members), I published a paper on the electromagnetic fields of a line current in the presence of a homogeneous cylinder (Wait, 1952). Although the general solution presented there was correct, an omission occurred in the reduction to the quasi-static form. Indeed, Ward and Hohmann (1988) indicated the corresponding expression for qn in my 1952 paper was “wrong” after they had replicated my general derivation. Also, they correctly pointed out that I should not have omitted the n = 0 term in the series expansion for qn in the quasi-static limit.
