The paper studies the diffraction behavior of the millimeter-wave by illuminating a cylindrical metallic rod with 60, 90, and 120 GHz Gaussian beams to investigate what would its diffraction image look like. For each frequency, the diffraction was repeated with four different distances between the rod and the detector, i.e., 9.5, 22, 31, and 39.5 𝑐𝑚. The author employed Igor Pro to plot all diffraction patterns using the data collected by the detector attached to a rotary stage, analyzed these patterns by computing their corresponding Fresnel numbers, and suggested future works based on the finding.
