Physics Based Triple Debye Dielectric Modeling and Multi Layer ADE FDTD Simulation of Terahertz Pulse Reflection for Breast Cancer Detection
Ali Asghar Molavi Choobini, Mehran Shahmansouri
Terahertz (THz) imaging has emerged as a promising non-ionizing modality for breast cancer assessment owing to its intrinsic sensitivity to tissue hydration. However, existing diel…
Theoretical Analysis and PIC Simulations of Electromagnetic Wakefields Excited by Relativistic Beams in Magnetized Plasmas
Ali Asghar Molavi Choobini, Mehran Shahmansouri
This study presents theoretical and numerical investigation of the coupled longitudinal and radial wakefields excited by ultrarelativistic electron beams propagating through a cold…
Optical surface plasmons at a metal-crystal interface with the Drude-Lorentz model for material permittivity
A. P. Misra, M. Shahmansouri, N. Khoddam
The theory of surface electromagnetic waves (SEMWs) propagating at optical frequencies along the interface of an isotropic noble metal [e.g., gold (Au)] and a uniaxial crystal [e.g…
Surface plasmons in a semi-bounded massless Dirac plasma
M. Shahmansouri, R. Aboltaman, A. P. Misra
The collective excitation of surface plasmons in a massless Dirac plasma (e.g., graphene) half-space (bounded by air) is investigated using a relativistic quantum fluid model. The…
Surface plasmon oscillations in a semi-bounded semiconductor plasma
M. Shamansouri, A. P. Misra
We study the dispersion properties of surface plasmon oscillations in a semi-bounded semiconductor plasma with the effects of the Coulomb exchange force associated with the spin po…
Modulation and nonlinear evolution of multi-dimensional Langmuir wave envelopes in a relativistic plasma
M. Shahmansouri, A. P. Misra
The modulational instability (MI) and the evolution of weakly nonlinear two-dimensional (2D) Langmuir wave (LW) packets are studied in an unmagnetized collisionless plasma with wea…
Elliptically polarized electromagnetic waves in a magnetized quantum electron-positron plasma with effects of exchange-correlation
M. Shahmansouri, A. P. Misra
The dispersion properties of elliptically polarized electromagnetic (EM) waves in a magnetized electron-positron-pair (EP-pair) plasma are studied with the effects of particle disp…
