whose solutions are zero order Bessel functions (or linear combinations 

 thereof) of a kind depending on the region under consideration. Thus 

 if jS > (Si , and the region occupied by the medium includes the cylinder 

 a.xis, the modified Bessel function /o {r\^f3- — /3i^) has to be chosen if 

 the field is to be finite at r — 0; if the medium extends from a finite r 

 to infinity, the function A'o (r\/j3'^ — j3i'^), regular at infinity, is se- 

 lected. Correspondingly, if /3 < |Si , the Bessel and Hankcl function 

 Ju (r\^l3i- — I3-) and Ho^' ' (r -x/jSi^ — I3-) replace h and /vo respectively. 

 In terms of the appropriate solution of (21), the remaining field com- 

 ponents are
