Abstract :
A new type of periodical chirowaveguide is proposed in the paper. A numerical approach for solving the problem, which is a combination of the mode expansion method and the least-squares boundary residual method is developed. Canonical examples are presented to show the validity and usefulness of the method. The novel features of the new type of waveguide are also shown. To help design band-reject filters and leaky-wave antennas, some theoretical curves and useful conclusions are presented
