Electromagnetic Scattering From Strips Using the Subdomain Approach

Infinitely thin multiple strip scattering problems are studied using the subdomain approach for two-dimensional (2-D) transverse magnetic and transverse electric excitations. The subdomain approach divides the entire domain into several partially overlapping subdomains, within which fields are expan...

Description
Summary:Infinitely thin multiple strip scattering problems are studied using the subdomain approach for two-dimensional (2-D) transverse magnetic and transverse electric excitations. The subdomain approach divides the entire domain into several partially overlapping subdomains, within which fields are expanded by classical techniques. The mode-matching method is used to impose continuity conditions. Results are validated by comparing to numerical results from COMSOL. Results show that the subdomain approach can be as accurate as the numerical solutions and may offer substantial improvements in efficiency.
