In this article, we report a critical assessment of dielectric function calculations in electron gas through the comparison of different modelling methods. This work is motivated by the fact that the dielectric function is a key quantity in the multi

International audience; Plasmon excitation within multiple scattering approach is being explored. The plasmon loss is described within the so-called quasi-boson approximation, originally proposed by Hedin and further extended by Fujikawa. We compare

Ultramafic and mafic rocks occur within a linear belt, trending nearly E–W along North Puruliya Shear Zone of the Chhotanagpur Gneissic Complex (CGC). These rocks are classified as gabbro, norite, gabbro-norite, dolerite, diorite, olivine-websterit

Petrology of mafic-ultramafic rocks along North Puruliya Shear zone, West Bengal

Autor: Arijit Ray, Aditi Mandal

Publikováno v: Journal of the Geological Society of India. 74:108-118

The North Puruliya Shear zone (NPSZ) is characterized by occurrence of mafic-ultramafic rocks aligned parallel to the shear zone, intruding the high grade Proterozoic rocks of Chhotanagpur Gneissic Complex. The ultramafic rocks occur as small lenses,

Microstrip antennas are excited for radiation modes using different techniques which lead to best impedance matching between the feed line and the patch. This paper describes two techniques which use microstrip line and also coaxial line as feed line
