Growing electrostatic modes in the isothermal pair plasma of the pulsar magnetosphere

U. A., Mofiz; Amin, Md. Ruhul; Shukła, Padma Kant (© 2011 Springer Science+Business Media B.V., 2012)

It is shown that a strongly magnetized isothermal pair plasma near the surface of a pulsar supports low-frequency (in comparison to electron cyclotron frequency) toroidal electrostatic plasma modes in the equatorial region. ...
Langmuir dark solitons in dense ultrarelativistic electron-positron gravito-plasma in pulsar magnetosphere

U. A., Mofiz; Amin, M. R. (© 2013 Springer, 2013)

Nonlinear propagation of electrostatic modes in ultrarelativistic dense elelectron-positron gravito-plasma at the polar cap region of pulsar magnetosphere is considered. A nonlinear Schrödinger equation is obtained from ...
Optical solitons in negative-index meta-materials

U. A., Mofiz (© 2013 IEEE, 2013)

The nonlinear propagation of gigahertz electromagnetic wave propagation in the resonant region of a negative index meta-material is investigated. It is found that the negative refractive index is maintained within a narrow ...
