EMA has experience in all aspects of electromagnetic pulse (EMP). EMA developed 3D and cable codes for EMP interaction and modeling
EMA’s services team provide solutions to companies in the domain of electromagnetic environmental effects (E3), electromagnetic compatibility (EMC), survivability in the space radiation environment, and in radio frequency interference (RFI) problems. EMA’s consultants provide simulation and test support...
Sintered iron and iron-Si powders are used widely in automotive DC applications. This presentation details the current state of the technology in non-sintered soft magnetic composites. High resistive coatings developed recently allow these products to be competitive with Fe-Si lamination steels in ...
A micromechanics approach is developed to analyze the average fields and effective moduli of heterogeneous media that exhibit full coupling between stationary elastic, electric, and magnetic fields. Exact relations regarding the internal field distribution inside a heterogeneous magnetoelectroelastic solid are...
whichever is more suitable for the application. Oil cooled magnets are fitted with expansion tanks to ensure the coil is always immersed in oil and is furnished with breather and sight glass. All are furnished with heavy-duty non-magnetic impact plates to withstand heavy impact of extracted iron...
In the first Case-I, the applied electric and magnetic fields are mutually parallel and normal to the EMR fluid flow direction. Next, in Case-II, the applied electric field is mutually perpendicular to the magnetic field and parallel to the EMR fluid flow direction. At last, in Case-III,...
A magneto-trapped carrier effect induced by BaFe12O19 hard-magnetic nanoparticles (NPs) is discovered, which can lower the carrier concentration of n-type Bi2Te2.5Se0.5 matrix by 16%, and increase the Seebeck coefficient by 16%. Meanwhile, BaFe12O19 NPs provide phonon scattering centers and ...
Effect of electroflotation on quartz and magnetite and its utilization on the reverse flotation of magnetic separateion concentrate. Miner. Eng. 2022, 175, 107292. [Google Scholar] Sarkar, M.S.K.A.; Donne, S.W.; Evans, G.M. Utilization of hydrogen in electroflotation of silica. Adv. ...
Electrochemiluminescence (ECL) is a light-emitting process triggered by the high energy redox between electrochemically oxidized and reduced luminophores or some coreactive intermediate radicals, representing a blooming hot topic over decades with a wide variety of bioanalytical applications. Due to the ...
