on the source of plasma density and electric field perturbations in pmse and pmwe regionspolar mesospheric summer/winter echoes (pmse/pmwe) are very strong radar echoes produced by ionospheric electron density fluctuations at half the radar wavelength. the main focus of this paper is the altitude range 80 to 90 km in summer and altitude range 65-86 km in winter in the polar mesosphere . this pa...

magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (cnts) is studied. the cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. the mori-tanaka model is used for obtaining the equivalent material properties of the cylinder. based on the ch...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

Electricfield distributions measured using the Kerr effect cause a phase,shift between light components polarized parallel and perpendicular to the electric field, proportional to the magnitude sqyared of the electric field components in the plane perpendicdar to light propagation integrated over the light path length. One wishes to recover the electric field distribution from m4asurements of l...

Abstract: Presence of externally applied electric field can cause the flow field in the micron and submicron channels; this generated flow field is called electroosmotic. In this type of flow field, the presence of the external electric field causes the extra generated heat in the domain that may affect the performance of the system (Joule heating effect). In the present study, an analytical ap...
