Magnetic iron oxide nanoparticles (Fe3O4) can be dispersed in a supporting material so that the composite better respond to electromagnetic fields, absorbing part of their energy. In discussion here proposed we will consider role these applications for interference (EMI) shielding. Inserted intrinsically conducting polymers (ICPs) instance, are increasing EMI shielding effectiveness polymer, pr...

The plasma shielding effect is a well-known mechanism in laser-produced plasmas (LPPs) reducing laser photon transmission to the target and, as a result, significantly reducing target heating and erosion. The shielding effect is less pronounced at low laser intensities, when low evaporation rate together with vapour/plasma expansion processes prevent establishment of a dense plasma layer above ...

Abstract The multi-walled carbon nanotubes (MWCNTs) and the poly(acrylonitrile-co-butadiene-co-styrene) (ABS) granulates are dispersed in acetone separately using a magnetic stirrer followed by ultrasonication. Further, both solutions were mixed with stirring Neat-ABS film, 0.25 wt%, 0.5 wt% 1 of MWCNT-ABS nanocomposite films average thickness 140 µm fabricated solution molding petri dish, room...

Electromagnetic compatibility (EMC) has become much more important especially over the last decade due to incorporating advanced driver assistance and electric propulsion systems into conventional vehicle architecture. shielding is a conductive barrier used for protecting electronic circuits against external electromagnetic interference (EMI). Shielding effectiveness (SE) measure of performance...

Interplanetary space radiation poses a serious health hazard in long-term manned space missions. Natural Martian surface materials are evaluated for their potential use as radiation shields for manned Mars missions. The modified radiation fluences behind various kinds of Martian rocks and regolith are determined by solving the Boltzmann equation using NASA Langley’s HZETRN code along with the 1...

A hybrid method of subgrid FDTD(2,2) with FDTD(2,4) is presented. Both the standard FDTD(2,2) as well as the hybrid technique are applied to shielding effectiveness analysis of a scaled model of a Boeing 757. Also, analysis of EMI generated by personal electronic devices is performed on the same scaled fuselage model.
