Numerical Characterization of Rectangular Waveguide in Free Space using HFSS Software at Lower Microwave Frequencies
نویسندگان
چکیده
Guiding characteristics along with field distributions for different modes in a rectangular waveguide are numerically estimated using HFSS software when it is placed in free space. A comparative analysis is made for propagation constant, guided wavelength and characteristic impedance at C, X and Ku band to observe the deviation from well-known theoretical profiles. Strength of electric and magnetic fields at microwave region is analyzed inside the waveguide along with fundamental four modal distributions. Characteristic profiles are useful for analyzing performance of rectangular waveguide for a particular frequency region. Simulations are carried out using HFSS software and compared with theoretical results obtained from MATLAB which speaks about its accuracy for designing and analyzing complex microwave passive devices. Keywords— Characteristic Impedance, Field Intensity, HFSS®, MATLAB®, Propagation Constant, Rectangular Waveguide.

A Full-Height Waveguide to Thinfilm Microstrip Transition
Excellent progress in the development of Submillimeter-wave SIS and HEBmixers has been demonstrated in recent years. At frequencies below 800 GHz these mixers are typically implemented using waveguide techniques, while above 800 GHz quasi-optical (open structure) methods are often used. The choice of waveguide offers several advantages over quasi-optical techniques, such as the use of broadband...
