Paper Title
Rectangular Waveguide Characterization Using HFSS

The rectangular waveguide characteristics and field distribution for different modes in an open ended rectangular waveguide when the waveguide is in the free space is computed using HFSS software. The analysis is made for different parameters. The electric and magnetic fields strengths are analyzed inside a rectangular waveguide along with fundamental modal distributions. Simulation analysis is carried out for X-band. Characteristic profiles are analyzed and the performance of rectangular waveguide is studied. Theoretical analysis and simulation are carried out for waveguide and both results are compared. A HFSS simulation platform for the analysis of the aperture radiation from a dielectric filled rectangular waveguide is described.
