摘要：

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
