| dc.description.abstract | Ridged waveguides have found many applications as microwave and millimeter-wave components. Their advantages include large single mode broadband operation and large fundamental mode cutoff wavelength. The study of ridged waveguides may be traced back to the 1940s. Since then, new ridged waveguide structures and new numerical computational techniques have been proposed and studied extensively. In this thesis, some new ridged waveguide structures, including a circular waveguide loaded with two T-shaped septa, a triple ridge loaded trough rectangular waveguide and a cross ridge loaded trough rectangular waveguide are proposed and theoretically analyzed by using the Finite Element Method (FEM). This analysis is verified by comparing the results with existing results from various sources. Numerical results are presented demonstrating that these structures offer a significant increase in fundamental mode cutoff wavelength and bandwidth when compared to various unloaded and loaded waveguides. These new structures can be used in the design , of compact and wide-band microwave and millimeter-wave passive components and monolithic microwave integrated circuits (NIMIC). An independent FEM analysis program for solving eigenvalue problems in 2-dimensional domain is developed to satisfy one of the objectives of this thesis. This program is the basis of a proposed 3-dimensional analysis program using the mode matching method. | |
