Excitation of multilayered plasma columns with the ring of magnetic currents

The excitation of gaseous plasma column having semiconductor plasma columns on either side is studied with the excitation source being the ring of magnetic currents. The whole structure being cylindrical in shape, contains the conductor along its axis. The effect of radii of all the columns including that of the ring of radiation pattern, is studied which shows a peak of maximum radiation in a certain direction along with some other less intense peaks. In most cases the peak occurs roughly at 61deg at which fine structure is given. Also three intense peaks of radiation occur when radius of the plasma (outer semiconductor) column is 0.058 m. (author)
