THE NEED To design and verify measurements of a variety of antennas THE SOLUTION HFSS™ Amedeo Larussi, of Raytheon, uses HFSS™ to design and validate antennas. When presenting his methods at one of Ansoft’s HFSS Users Workshops, Larussi discussed the following elements crucial to his design: Electromagnetic numerical methods, including fintite element, finite difference, moment method, and other methods (i.e., mode matching, fourier, etc.) Circular waveguide design problem setup with higher order modes, including geometry generation, material assignment, boundary setup (higher order modes), and solution/result interpretation Reflector and feeds design problem, including dual polarization feed and reflector geometry generation, material and boundary assignment, solution, and large-size reflector and feed modeling with HFSS Radome and other dielectrics design problem, including luneberg lens’s geometry setup, material setup with variable index of refraction, and result discussion of HFSS versus other theoretical prediction « Back to Preview Front Page
