“…One of the studied issues is the propagation of non-twisted electromagnetic waves and minimizing energy losses in a rectangular waveguide filled with inhomogeneous movable plasma, considering relativistic effects. [22] Nevertheless, electron acceleration by the interaction of twisted electromagnetic waves and plasma will involve attractive and complex phenomena, and we intend to address them in this study. [1] In this paper, an advanced mathematical method modeled the acceleration of a relativistic electron in a cylindrical waveguide filled with warm and motional plasma.…”

This paper studies the acceleration of an electron in a magnetized plasma waveguide caused by the interaction between the twisted electromagnetic wave and the plasma wave in a motional plasma. The spatial dependence of the amplitude and phase of the twisted TM mode has been derived by solving the wave equation. With appropriately assigned initial values, total electron energy gain can be calculated using numerical calculations. Numerical results show that plasma motion, as long as the twisted electromagnetic wave pulse, significantly affects electron acceleration during an electron's passage through the waveguide.

“…The excitation of an EM wave by a relativistic electron beam (REB) in a plasma-filled waveguide with warmness and magnetization effects has been investigated [7]. The inhomogeneous plasma filling the rectangular waveguide has been studied to minimize energy losses under the REB effect [8]. The REB styles with ion-channel guiding and waveguide prevalence have been investigated [9], [10].…”

The possibility of generating an electromagnetic (EM) wave by a free-electron laser (FEL) beam from the Cherenkov device to control the cylindrical waveguide's field attenuation filled with plasma has been investigated by analytical formalism. This new study sheds light on Cherenkov FEL (C-FEL) beam interaction with electrons of inhomogeneous warm plasma to generate an EM wave in fractional dimensional space. The new analysis of traveling and standing waves in terms of Hankel and Bessel functions paves a way for introducing controlled EM wave propagation based on fractional D-dimensional space. It has been found that the C-FEL beam excites the EM wave and enhances the propagation of the electrical field through fractional dimensional space with propagation constant depending on the Langmuir frequency. Within the plasma in the cylindrical waveguide, a TM mode emerges, which contains spatial frequencies with a faster growth rate for traveling waves than standing waves.

“…The surface wave produced between plasma metal interface are characterized by terms of plasma parameters such as plasma electron density, collisional frequency for their exceptionally tuneability whether external magnetic field present or absent in plasma [21,22]. The plasma material is highly desirable as compared to other dielectric materials which are expensive, difficult to handle, fragile to produce surface wave [23][24][25][26][27][28]. The scientists are eagerly engaged in advance research to improve the ability of biosensor for detection of cancer.…”

This manuscript investigates the properties of surface plasmon polaritons (SPPs) at anisotropic plasma metal interface. It has been shown that magnetized plasma surface plasmon waves have unique features such as hybridization nature, the existence of cutoff frequency and the dependence of normalized prorogation constant and prorogation length on plasma parameters such as cyclotron frequencies (𝜔𝑐) and plasma frequency (𝜔𝑝). The influence of plasma features on normalized propagation constant and propagation as the function of frequency under different values of plasma frequency and cyclotron frequencies are studied. This suggest SPPs at magnetized plasma metal interface may be exploited for Plasma-on-Chip for cancer treatment.
