Measurement of Temperature Changes in PMMA Using Digital Holographic Interferometry
Volume 2, Issue 3 , March 2018, Pages 9-14
Abstract
Holographic interferometry is one of the accurate methods for measuring physical quantities such as stress, pressure, vibration, and temperature and refractive index changes especially in transparent solid materials. In this study, a digital Mach-Zehnder holographic interferometry setup was used to measure ...

Volume 2, Issue 3 , March 2018, Pages 15-22
Abstract
In this work, we report on update and automation of an old-fashioned interferometer by using image processing techniques and developing a Graphical User Interface (GUI) in the MATLAB environment. After updating the system and receiving the digital images of interference fringe patterns from the interferometer ... Read MoreComparison of Energy Gain in Laser and Magnetic Fusion
Volume 2, Issue 3 , March 2018, Pages 23-30
Abstract
In this paper the zero-dimensional nonlinear transport model is applied to obtain the energy and the densities of deuterium and tritium fuel ions, as well as the alpha-particles in fusion reactor for laser and magnetic confinement methods. In this work D-T fuel pllets with. KrF laser is used in laser ... Read MoreDynamics of pulse propagation in gas-filled hollow-core photonic crystal fibers
Volume 2, Issue 3 , March 2018, Pages 31-36
Abstract
As a new approach based on a multiple scale perturbation theory, we have founded clearly that ionization in a hollow-core photonic crystal fiber filled by an ionizable gas leads to a soliton self-frequency blueshift, opposite to redshift due to Raman self-frequency. To analyze the hollow-core photonic ... Read MoreStudy of TM surface waves in metamaterial photonic crystals with self-defocusing uniaxial nonlinear cap layer
Volume 2, Issue 3 , March 2018, Pages 37-44
Abstract
In this paper, we have analytically investigated the TM surface waves (SWs) by using the first integral of Maxwell’s equations in a semi-infinite one-dimensional photonic crystal (1DPC) which is truncated with the self-defocusing uniaxial nonlinear cap layer. We have studied the considered 1DPC ... Read MoreEffects of density and energy difference of two beams on the picks growth rate in a two-stream free electron laser
Volume 2, Issue 3 , March 2018, Pages 45-52
Abstract
By linearizing and using Floquet’s theorem Maxwell equations, continuity and momentum equations are solved. Dispersion relation (DR) of a two stream free electron laser (FEL) with a helical wiggler pump is obtained. The DR which shows coupling of all modes is derived with using a fluid approach. ...

Volume 2, Issue 3 , March 2018, Pages 53-60
Abstract
Abstract: If the dielectric between two superconductors of the Josephson junction is homogeneous the governing equation for the phase of the system can be described by the sine-Gordon equation. In this paper, we consider inhomogeneous dielectric medium, such that the dielectric constant is position dependent. ...
