Asif Alam holds two granted United States patents in millimeter wave waveguide transition technology, both granted in 2025. One of these patents was awarded a Gold Medal at the 50th International Exhibition of Inventions Geneva.
This patent covers a systematic design method and apparatus for connecting rectangular waveguide structures to air-filled substrate integrated waveguides at millimeter wave frequencies. The innovation addresses one of the most technically demanding interfaces in high-frequency RF hardware by replacing iterative trial-and-error design approaches with analytical equations, enabling engineers to build wide-band transitions correctly from first principles.
