Radiation through cylindrical plasma sheaths

The rad iation fi elds of a magnetic lin e source axially orien ted on a conducting cylinder which is i n a plas ma e nviron ment have been analytically determined.The plasma environment is taken to be a seri es of homogeneous cylindrical layers none of which is co n tiguous with the cylin der .It is demonstrated t hat a quite significa nt d istortion of t he field pattern is e ffected by t he prese nce of a lossless plas ma sheath.Characteristics of t he rad iation fi elds are di sc ussed a nd rad iation pattern s, computed in a pla ne t hrough t he axis of the cylin der and the line so urce, a re presen ted.The patterns are found to have large narrow amplitude flu ctuatio ns t hat can be attri buted to lea ky waves.
