“…Over the years, numerous terahertz imaging techniques for cancer detection have been developed. These techniques encompass various approaches, such as mammography, pulsed systems, reflect emission, and other methodologies, targeting different types of cancer [18][19][20][21][22][23][24] . Several of these approaches have been dedicated to breast cancer imaging, although they may also incorporate techniques applicable to other cancer types [25][26][27][28][29][30][31][32][33] .…”

Terahertz emerges as a promising cancer imaging technique. Many factors can cause imaging results, including polarization and different tissue types. This research discusses the effect of wave polarization and different tissue types. The imaging results with perpendicularly two linear polarization give the best imaging results qualitatively and quantitatively with a standard deviation of 7.519. Different tissue types affect the imaging results, but the effect is not linear with the increasing dielectric constant. This research can be used as a consideration and reference for other researchers developing a THz imaging system.

“…Fast simulation methods for modeling the carrier transport in semiconductors are presented in [3][4]. In a millimeter-wave band and for all applications, the size of the structure affects the performance and the wave propagations must be taken into account for modeling purposes [5]. The availability of a reliable simulation tool in a high-frequency design chain reduces the number of design cycles, shortens the design time, and reduces the design cost.…”

In this study, the transmission line concept and the electron transport theory are consolidated in a global modeling approach, the wave-electron-transport (WET) model, to account for the physical phenomena in millimeter-wave devices. No equivalent circuit model is required to represent the innate properties of the device. Hence, the model is reliable for both small-and large-signal analyses. The electrodes of a transistor act as coupled multi-conductor transmission lines at millimeter-wave bands. The WET model consists of a device solver to obtain solutions for carrier-transport equations of the intrinsic device, and an electromagnetic solver (EM solver) to provide solutions for the governing transmission lines equations. As it is crucial to transfer data between these two solvers, an interface scheme is also developed and included in the WET model. The extrinsic parameters of the device are extracted using a novel systematic technique merely based on the physical structure of the transistor. In this paper, the modeling procedure is applied to a fabricated GaN-HEMT device. Power sweep analysis has verified the accuracy of the proposed model under both linear and non-linear operations. Non-uniform voltage distribution caused by traveling waves over the electrodes is elaborately discussed to demonstrate the necessity of incorporating distributed effects.INDEX TERMS Electromagnetic-wave propagations, millimeter-wave transistor, non-linear operations, transmission line concept, wave-electron-transport model.
