Quasioptical calibration methods were applied to de-embed the impact of cryostat and optical elements on device under test measurements. The devices were measured through vacuum windows via focused beam radiation. A de-embedding method employing line-reflect-match (LRM) calibration was established to account for the effects of optical components and vacuum windows. Such a method does not require multiple line standards inside the cryostat and mechanical translation of quasioptics. System validation was performed with measurements of cryogenically cooled devices, such as bare silicon wafers and stainless-steel frequency-selective surface (FSS) bandpass filters, and superconducting bandpass FSS fabricated in niobium. A permittivity reduction of Si based on a 4 GHz resonance shift was observed concomitant with a drop in temperature from 296 to 4.8 K. The stainless steel FSS measurements revealed a relatively temperature invariant center frequency and return loss level of 263 GHz and 35 dB on average, respectively. Finally, a center frequency of 257 GHz was measured with the superconducting filters, with return loss improved by 11 dB on average at 4.8 K. To the best of our knowledge, this is the first reported attempt to scale LRM calibration to 330 GHz and use it to de-embed the impact of optics and cryostat from cryogenically cooled device S-parameters.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 3","pages":"258-271"},"PeriodicalIF":3.9,"publicationDate":"2025-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11224641","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146216527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we present a simple and cost-effective new paradigm, the film-to-fiber method, utilizing commercial polyimide (PI) films to form a typical six-cladding-tube HCNCF structure. Additionally, metal microstructures can be integrated onto the PI film to enhance waveguiding properties. Three HCNCF types—without metal structures, with full metal integration, and with selective metal placement—are fabricated and characterized using terahertz time-domain spectroscopy system across 0.2–1.5 THz. Experimental results, including experimental loss, refractive index (birefringence), dispersion, and other parameters, align well with numerical simulations. This study introduces a cost-effective and flexible fabrication approach that accommodates polymer films of arbitrary thickness, providing a new paradigm for HCNCF manufacturing and advancing terahertz applications.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 3","pages":"318-330"},"PeriodicalIF":3.9,"publicationDate":"2025-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146216536","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}

However, the high propagation losses and poor penetration inherent to THz waves restricted its development. Wavefront manipulation techniques for beam steering to redirect the propagation directions are essential for mitigating these limitations. In this article, cross-polarization conversion-based phase engineering for THz reflective beam steering is presented. This approach has the advantages of enabling quasi-linear phase response with sufficient phase-shifting range and maintaining high reflection magnitudes over a wide frequency band. Furthermore, a four-port equivalent circuit is developed to explain the design principle and verify the effectiveness of the polarizers. As a result, the metasurfaces composed of the proposed unit cells achieve stable wide-angle beam steering with high reflection intensity and have continuous frequency-scanning capability. In addition, the metasurfaces are verified to support the high-quality quadrature amplitude modulation with 16 states with an acceptable power penalty in a non-line-of-sight THz link.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 3","pages":"307-317"},"PeriodicalIF":3.9,"publicationDate":"2025-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146216617","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}

The frequency sixtupler, implemented in indium phosphide (InP) 250-nm double heterojunction bipolar transistor (DHBT) technology consists of a frequency tripler and a frequency doubler, both driven by amplifiers to provide sufficient power. The sixtupler operates across the full D-band by driving the multipliers with sufficient power for the saturated output power and using a doubly-tuned transformer for wideband frequency matching. The sixtupler MMIC is then packaged into a split-block waveguide module with an E-plane probe on a quartz substrate for a microstrip-to-waveguide transition. The transition coupler is designed to compensate for impedance mismatch caused by a bond-wire. Measured output power ranges from 2.7 to 9.8 dBm from the on-wafer test and –1.9 to 8.1 dBm from the waveguide module test, respectively, across the full D-band.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"16 3","pages":"347-351"},"PeriodicalIF":3.9,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146216532","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}
