Abstract
Modern commercial applications increasingly rely on advanced communication and sensing capabilities to make autonomous, real-time decisions. This trend continually pushes the demand for higher data communication rates and finer sensing resolution.
Meeting these requirements using the currently allocated microwave spectrum has become challenging due to limited available bandwidth and the physical constraints associated with longer wavelengths. Consequently, both research and, more recently, commercial applications have been shifting toward higher-frequency spectrum ranges, where wider bandwidths and shorter wavelengths can be exploited. To support this transition, numerous studies have been published in recent years, documenting significant progress in the electronic device development cycle. Nevertheless, despite these advances, several areas still require improvement. This thesis addresses some of the persistent limitations in the measurement and characterization of electronic devices (both before and after fabrication) where the community continues to rely on low-frequency methods, techniques, or data extrapolated from lower frequencies and applied at higher frequencies....
