Abstract: The present study deals with the propagation of electromagnetic
fields and power in a circular waveguide, with DB-boundary conditions,
internally coated with chiral-nihility medium. The two layer circular waveguide
defined by DB-boundary conditions, with one layer containing free space while
other layer containing chiral-nihility medium, is investigated. DB-boundary
conditions require vanishing of normal field components of the D and B vectors, hence termed as
DB-boundary conditions. It has been studied that there is non-zero electric and
magnetic fields in free space as well as in chiral-nihility medium in a
circular waveguide defined by DB-boundary conditions. Hence, there is non-zero
power transfer both in nihility as well as non-nihility regions
Keywords: DB boundary conditions, chiral-nihility medium, circular waveguide
