This paper presents a comprehensive investigation of solid and hollow polymer-based near-field imaging probes, each coated with a metallic layer on the outer surface, designed to operate in the THz frequency range. These probes are tailored to exploit the near-field properties of THz radiation for achieving sub-wavelength resolution imaging. The proposed probes exhibit a versatile design that has been rigorously examined through advanced electromagnetic simulations. The solid probe focuses on exploiting the dielectric properties of the material to manipulate THz radiation. Conversely, the hollow probe leverages its cavity structure to create resonant modes within the THz frequency range. This resonance phenomenon enhances the probe's ability to guide THz radiation, resulting in superior imaging capabilities. The metallic coating further enhances performance by efficiently coupling with THz waves, leading to improved resolution and signal-to-noise ratios. Overall, this paper presents a thorough investigation of solid and hollow polymer-based THz near-field imaging probes and experimentally demonstrates their effectiveness for high-resolution sub-wavelength imaging applications. These 3D printable probes offer versatile, cost-effective, and disposable imaging solutions for non-destructive material evaluation and sub-cellular scale imaging in various domains.

“…It does not cause any ionization hazard on biological samples due to the low energy of THz radiation. Recent investigations suggest that the TPI method can be used in the early identification of medical tablets using techniques that rely on X-rays [1] [2]. The terahertz imaging (TI) system is developed for dental diagnosis, due to essential advantages in medical studies.…”

Recently a lot of medical tablets with special packets in the global market are available. For the safety and purity of the tablet, we need to scan it by developed scanner technology, which should be not more expensive and easily available in the market. The THz technology is one of them. In the proposed work, we have tasted tablet images with the help of the THz super-resolution scanner, which is already available in our lab. The AI machine learning data concept has been investigated. Good resolution of images has been obtained. Furthermore, the challenging research problems are discussed. Finally, it summarizes the recent updates in terahertz technology for drug inspection and medical applications with potential research challenges.

“…In particular, methods for noninvasive glucose level monitoring using THz radiation are being developed [9,10]. Moreover, the possibility to examine teeth caries using THz waves has been shown [11]. Besides, as THz radiation is characterized by the strong water absorption [12], this frequency range can be used as a sensitive and precise non-invasive hydration probe, in particular, to monitor biotissue dehydration [13,14].…”

We apply terahertz time-domain spectroscopy for the quantitative non-invasive assessment of the water content in biological samples, such as tree leaves and pork muscles. The developed experimental terahertz time-domain spectroscopy system operates both in transmission and reflection modes. The Landau-Looyenga-Lifshitz-based model is used for the calculation of the water concentration within the samples. The results of the water concentration measurements are compared with the results of the gravimetric measurements. The obtained results show that the water content in biological samples can be measured non-invasively, with a high accuracy, utilizing terahertz waves in transmission and reflection modes.
