Based on the statistics of 20 female patients, we demonstrate that the diagnostic sensitivity and specificity of the THz fiber-scanning near-field microscopy to examine breast tumor sections are all as high as 100%. It will be very useful for quick definition of the tumor margins during the surgical procedure such as breast-conserving surgery.
We successfully established a compact all-THz fiber-scanning near-field microscope operating at room-temperature. This upright transmission-illumination microscope was applied for diagnosis of breast tumor biopsy samples with ~100% specificity and ~100% sensitivity.
We demonstrate a terahertz (THz) directional coupler for future THz applications including THz power dividers, THz communications, and THz fiber-endoscopes. By using subwavelength polyethylene fibers, we successfully established a single-mode fiber-based THz directional coupler. Unlike traditional directional couplers, the demonstrated subwavelength directional fiber coupler shows less dependency...
We demonstrate a continuous-wave THz fiber-endoscopy by utilizing low-loss THz subwavelength plastic fibers. The reconstructed 3D images not only reflect the depth variation of the object surface, but also reveal the molecular distribution of samples.
By adopting a novel CPW-fed rampart slot array antenna, we demonstrate a compact highly-directed THz photonic transmitter with a single photodetector source. 3dB radiation beam widths in both E- and H-planes are significantly reduced.
