The work presents a novel passive probe antenna that can be operated at terahertz (0.1 THz) frequencies using a simple, purely passive structure. The antenna consists of a slender metal wire backed by a discontinuous phase plate that converts an ordinary linearly‑polarized free‑space beam into a…
The study demonstrates that millimetre‑wave guided modes—known as Sommerfeld waves—can be efficiently launched and transported along simple metallic wires at 100 GHz and 300 GHz. By inserting a straightforward differential phase plate in front of the wire, the researchers achieved a theoretical…
The study demonstrates that terahertz (THz) time‑domain spectroscopy can detect measurable changes in the optical properties of blood plasma from mice bearing Ehrlich carcinoma, offering a rapid, non‑invasive diagnostic approach for oncological disease. By measuring the refractive index and…
The pilot research demonstrates that terahertz (THz) imaging in the 300‑600 GHz band can reliably distinguish between malignant and healthy breast tissues within freshly excised specimens. Because the refractive index of cancerous tissue mixtures is measurably higher than that of fat or normal…
The study demonstrates that Electro‑Optical Probing (EOP), a non‑invasive laser‑based diagnostic technique, can be reliably applied to bipolar semiconductor devices to uncover internal electrical activity and identify failure mechanisms that are otherwise invisible to conventional analysis. By…

Executive Summary The research presented here delivers a novel room‑temperature terahertz (THz) sensor that converts incident electromagnetic power into a measurable electrical signal via a thermopile assembled on a micro‑fabricated silicon dioxide membrane. By using a metallic grid absorber…
The work presents a room‑temperature terahertz (THz) detector based on a thermopile that converts absorbed THz radiation into a measurable voltage. The sensor’s absorber is a metallic grid engineered through a multilayer theoretical model that accounts for diffraction and equivalent resistivity,…

Terahertz time‑domain imaging has been harnessed to generate refractive‑index maps of freshly excised breast tissue, enabling a non‑ionising, optical‑based assessment of tumour margins during breast‑conserving surgery. By converting the refractive‑index distribution into a binary map and then…
Hybrid Optical Bench for Innovative Teaching and learning (HOBIT) combines a physical optical table with a real‑time, self‑adaptive digital simulation and augmented‑reality overlays. The system enables any optical experiment to be assembled, adjusted, and observed in a single secure,…
