The rapid evolution of Radio Frequency (RF), millimeter-wave (mm-Wave), and Terahertz (THz) technologies has opened new frontiers in high-speed communication, advanced imaging, and non-invasive sensing. These frequencies, spanning from GHz to THz, offer an unprecedented combination of high data rates, fine spatial resolution, and the ability to penetrate materials in ways previously not possible. As the demand for next-generation wireless technologies such as 5G/6G, radar systems, and health diagnostics grows, it is essential that educators and researchers stay ahead of the curve.
