A Study on Angular Distribution of THz Radiation Driven by Two-Color Laser-induced Microplasma
Abolfazl Yousef-Zamanian, Mohammad Neshat
We present an analytical method to study the angular distribution of THz radiation driven by two-color laser-induced microplasma in nitrogen gas. Directionally dependent temporal w…
Reprogrammable Graphene-based Metasurface Mirror with Adaptive Focal Point for THz Imaging
Seyed Ehsan Hosseininejad, Kasra Rouhi, Mohammad Neshat +4
Recent emergence of metasurfaces has enabled the development of ultra-thin flat optical components through different wavefront shaping techniques at various wavelengths. However, d…
Developments in THz range ellipsometry
M. Neshat, N. P. Armitage
Ellipsometry is a technique whereby the measurement of the two orthogonal polarization components of light reflected at glancing incidence allows a characterization of the optical…
Terahertz time-domain spectroscopic ellipsometry: Instrumentation and calibration
Mohammad Neshat, N. P. Armitage
We present a new instrumentation and calibration procedure for terahertz time-domain spectroscopic ellipsometry (THz-TDSE) that is a newly established characterization technique. T…
Improved measurement of polarization state in terahertz polarization spectroscopy
M. Neshat, N. P. Armitage
A calibration scheme is presented for improved polarization state measurement of terahertz pulses. In this scheme the polarization response of a two-contact terahertz photoconducti…
Signal Recovery in Pulsed Terahertz Integrated Circuits
Abdorreza Heidari, Mohammad Neshat, Daryoosh Saeedkia +1
In this article, a time-domain calibration procedure is proposed for pulsed Terahertz Integrated Circuits (TIC) used in on-chip applications, where the conventional calibration met…
