EFFECTS OF ENVIRONMENT ON THE SURFACE WAVE CHARACTERISTICS OF A DIELECTRIC-COATED CONDUCTOR-PART IV

GLORY JOHN, R CHATTERJEE, S K CHATTERJEE

Abstract


The problem of excitation of multilayered-graded-dielectric-coated conductor by a magnetic ring source is formulated in the form of a contour integral which is solved by using the method of steepest descent. Numerical evaluation of launching efficiency shows that high value of about 90 percent can be attained by choosing proper dimensions of the launcher with respect to the dimension of the surface wave line.

Keywords
