Abstract

Summary form only given. Numerical Analysis has performed with MAGIC PIC code to investigate the influence of the outer conducting wall on eigenfrequency in a waveguide loaded with a tape helix. As it shown from the dispersion properties of the electromagnetic (EM) waves propagating through a tape helix located inside a waveguide, in the limiting case where the outer conducting wall is very close to the helix, the outer conducting wall completely eliminates the forbidden regions in the (/spl omega/, k) parameter space, and is independent of the width of the helix tape. The MAGIC analysis also shows the performance and characteristics of TAIT according to the variation of the distance between helix and conducting wall.
