To this goal, samples of phosphorus-doped silicon are characterized using terahertz time-domain spectroscopy (THz-TDS) in reflection. Four different samples span resistivities from <inline-formula><tex-math>$sim 0.04 - 50, {rm{Omega cm}}$</tex-math></inline-formula>, for temperatures ranging from room temperature to <inline-formula><tex-math>${{200}^{mathrm{o}}}{rm{ C}}$</tex-math></inline-formula>. The measurements confirm that the widely used Drude’s theory is adequate also to model the dispersion of silicon at higher temperatures. When comparing the corresponding scattering times obtained here using THz TDS pulses with the scattering time derived from the well accepted DC based empirical model of the mobility, differences emerge depending on the doping level. The scattering times predicted and measured are on the same order of magnitude and the anticipated reduction of the scattering time with increasing temperature has also been confirmed by the high frequency measurements. The absorptivity of the samples is also estimated accurately as a function of the frequency up to 1 THz.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 5","pages":"502-514"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147734708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we integrate chemical vapor deposition (CVD) graphene with a four-gap square ring metasurface to design an ultrasensitive THz sensor, where the specific current loop distribution and magnetic field confinement induce toroidal dipole resonance, resulting in a resonance peak in the transmission spectrum. By taking advantage of the ability of CVD graphene to shift its Fermi level toward the Dirac point under slight external stimulation, the proposed graphene-integrated toroidal dipole metasurface sensor achieves a detection limit of 126 pg/mL for prochloraz. Moreover, we employ a continuous wavelet transform to convert time-domain signals into 2-D wavelet coefficient intensity maps, enabling a more intuitive comparison of sensing performance with that of traditional 1-D methods. Meanwhile, we extract the maximum wavelet coefficient from the intensity maps and combine it with two 1-D parameters to construct a triangular-pyramid chart (TP-chart) for multidimensional analysis of sensing performance. This work provides an effective approach for trace-level detection, facilitating the application of terahertz technology in pesticide residue analysis.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 5","pages":"538-546"},"PeriodicalIF":3.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147734722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glide symmetry is introduced into the conventional domino-type SSPP transmission line to increase dispersion, thereby enabling a higher scanning rate. An asymmetric periodic modulation structure is designed to excite leaky-wave radiation while suppressing the open stopband effect without extra elements. A gap waveguide (GWG) is utilized as the feeding structure, which mitigates energy leakage from potential assembly gaps and significantly reduces fabrication difficulty and assembly complexity. The SSPPs and GWG structures are monolithically fabricated using high-precision 3-D printing and surface-metallized via magnetron sputtering of gold. Experimental measurements of a prototype demonstrate continuous beam scanning from -29<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula> to +49<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula> within the frequency range from 180 to 220 GHz, achieving a scanning rate of 3.9<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>/%BW. The peak gain varies between 11.13 and 16.53 dBi.
