Magnetic scaffolds (MagS) are 3-D composite materials, in which magnetic nanoparticles (MNPs) are used to load a polymeric matrix. Due to their wide use in several medical applications, there is an increasing demand of advanced techniques for nondestructive quality assessment procedures aimed at verifying the absence of defects and, more generally, dedicated to the characterization of MagS. In thi...Show More

A new type of eight-way multilayer power divider is presented in this article. To form the power divider, eight layers of the same substrate integrated waveguides (SIWs) are stacked together and inserted into a WR10 rectangular waveguide (RWG). In order to achieve a low-loss broadband response when connecting two substrates with different dielectric constants, a wedge structure is designed and app...Show More

Observation of Topological Transmission in Terahertz Domino Waveguide Array
Pan Hu;Lin Chen;Alexander Pavlovich Shkurinov;Yiming Zhu;Songlin Zhuang
Publication Year: 2023,Page(s):337 - 346
In this article, we propose on-chip terahertz (THz) domino waveguide array structures that can enable the topological effect and enhance the robustness of THz transmission. THz topological effect (include topologically protected edge states and binding states) is excited by constructing kink and antikink structures in designed domino waveguide arrays. Furthermore, the robustness of topological wav...Show More
Room Temperature Absolute Radiometer for Reproduction of Terahertz Radiant Power
Publication Year: 2023,Page(s):347 - 353
In this article, we propose an electrical substitution and laser calibration technique for reproduction of terahertz radiant power. With this technique, the equivalence of terahertz absorption and electrical heating in the absorber is corrected and accurate terahertz radiant power is reproduced. A two-cavity absolute radiometer was developed for accurate reproduction of terahertz radiant power wor...Show More

The reflectance (R) and transmittance (T) of Si and GaAs wafers irradiated by a 6 ns pulsed, 532 nm laser have been studied for s- and p-polarized 250 GHz radiation as a function of laser fluence and time. The measurements were carried out using precision timing of the R and T signals, allowing an accurate determination of the absorptance (A) where A = 1-R-T. Both wafers had a maximum reflectance ...Show More
Accurate Free-Space Measurement of Complex Permittivity With the Angular Spectrum Method

This study presents an analytical method based on the angular spectrum method to extract accurate intrinsic material properties from the S-parameter data obtained with a free-space measurement system. Instead of the widely used plane-wave model, the proposed method calculates the beam propagation and the interaction with a dielectric slab for any incident electric field using the angular spectrum ...Show More
Metasurface Optics With On-Axis Polarization Control for Terahertz Sensing Applications

Nondestructive testing (NDT) and imaging of materials with unknown properties are important applications of terahertz technology. Different contrast-forming methods are available to obtain diverse information on the imaged region, including intensity, color, phase, and polarization. Polarimetric imaging is relatively under-investigated owing to the difficulty in its implementation with complex opt...Show More

All-dielectric metasurfaces have aroused significant interest for terahertz (THz) absorption. However, traditional all-dielectric metasurfaces are usually not convenient to achieve dynamic modulation. To address this problem, we made a nanocomposite whose THz dielectric constant is responsive to light. A template printing method was used to pattern this nanocomposite on a flat substrate with a wid...Show More

Two-photon polymerization is a promising fabrication technique for complex 3-D structures operating at terahertz (THz) given its sub-$\mu$m resolution with hundreds of mm$^{3}$ print volume capability. However, standard photoresins exhibit unsuitably high THz absorption and have poor mechanical, chemical, and thermal stability. To address the latter three issues, a new photoresin (commercially kno...Show More
