Abstract
A plasma lamp for an electrodeless plasma lamp having a compact dielectric waveguide body. Example embodiments may use a shaped body to allow operation at a lower frequency (or at the same frequency with a body of smaller volume) than a solid cylindrical or rectangular waveguide body having the same dielectric constant. The diagonal or diameter of a cross section used for a particular frequency or range of frequencies may be reduced by shaping the waveguide.
