Microstructured fiber links for THz communications and their fabrication using infinity printing
Guofu Xu, Kathirvel Nallappan, Yang Cao +1
In this work, a novel infinity 3D printing technique is explored to fabricate continuous multi-meter-long low-loss near-zero dispersion suspended-core polypropylene fibers for appl…
Super-resolution Orthogonal Deterministic Imaging Technique for Terahertz Subwavelength Microscopy
Hichem Guerboukha, Yang Cao, Kathirvel Nallappan +1
Terahertz subwavelength imaging aims at developing THz microscopes able to resolve deeply subwavelength features. To improve the spatial resolution beyond the diffraction limit, a…
3D-printed Terahertz Photonic Bandgap Waveguide-based Fluidic Sensor
Yang Cao, Kathirvel Nallappan, Hichem Guerboukha +2
A Bragg waveguide-based resonant fluidic sensor operating in THz band is studied. A fused deposition modeling 3D printing technique is employed to fabricate the sensor where the li…
Channel Multiplexing in Wireless Terahertz Communications Using Orbital Angular Momentum States
Kathirvel Nallappan, Hichem Guerboukha, Mohamed Seghilani +3
We present design and experimental validation of the system for the generation of the Orbital Angular Momentum (OAM) states using 3D-printed low-loss metamaterial phase plates for…
Exploiting k-space - frequency duality in Fourier optics towards real-time compression-less terahertz imaging
Hichem Guerboukha, Kathirvel Nallappan, Maksim Skorobogatiy
We present theoretical formulation and experimental demonstration of a novel technique for the fast compression-less terahertz imaging based on the broadband Fourier optics. The te…
A Dynamically Reconfigurable Terahertz Array Antenna for Near-field Imaging Applications
Kathirvel Nallappan, Jingwen Li, Hichem Guerboukha +4
A proof of concept for high speed near-field imaging with sub-wavelength resolution using SLM is presented. An 8 channel THz detector array antenna with an electrode gap of 100 um…
