In the past years there was a huge interest in experimental and theoretical studies in the
area of few-optical-cycle pulses and in the broader fast growing field of the so-called …

There are many analytical methods for solving partial differential equations (PDEs), such as
the (G′ G)-expansion, the Ricatti transformation method, and many more. In this …

Weakly nonlinear propagation of pressure waves in initially quiescent compressible liquids
uniformly containing many spherical microbubbles is theoretically studied based on the …

The generalized nonlinear Schrödinger (GNLS) equation is solved numerically by a split-
step Fourier method. The first, second and fourth-order versions of the method are …

In this paper, the new travelling wave solutions of the (2+ 1)-dimensional extended Calogero-
Bogoyavlenskii-Schiff (ECBS) equation are investigated. The main aim of this work is to find …

The complex modified K dV (CMK dV) equation and the generalized K dV equation are
investigated by using the tanh method and the sine-cosine method. A variety of exact …

We demonstrate a new guiding regime termed endlessly mono-radial, in the proposed
annular core photonic crystal fiber (AC-PCF), whereby only modes of the fundamental radial …

Weakly nonlinear propagation of plane progressive pressure waves in an initially quiescent
liquid uniformly containing many spherical microbubbles is theoretically investigated …

The extension to the split-step Fourier method (SSFM) for Schrödinger-type pulse
propagation equations that we propose in this article is designed with the accurate …

Mid-infrared supercontinuum (SC) generation in normally dispersive photonic crystal fiber
(PCF) made of GeS 2-Ga 2 S 3-CsI chalcohalide glass, is theoretically investigated. The …
