Analytical investigation has been presented of the propagation of electromagnetic waves in a circular optical waveguide containing chiral nihility metamaterial. The waveguide under consideration has the inner region as free-space and the outer region as the chiral nihility metamaterial. The outer region of guide is coated with perfect magnetic conductor (PMC). It has been found that no net magnetic field exists in the chiral nihility region of the guide whereas the same exists in non-nihility (i.e. the free-space) region. The expressions corresponding to fields and power have been derived with the emphasis on the power pattern corresponding to the excitation of transverse electric modes in the guide.
