The shielding of RF MRI coils using double-sided EMI shield
We present, here, a device for shielding the RF MRI coils to eliminate their undesired radiation, and to restore the natural resonant frequency f0 in the presence of a biological sample. It is presented for a planar surface RF MRI coil. Nonetheless, this approach is also valid for conformal coils as well. Introduction The influence of any biological sample on an RF MRI coil results in a shift o...
متن کاملTitle : PMMA / carbon nanotube nanocomposites foams for EMI shielding application
With the rapid development of gigahertz electronic systems, electromagnetic pollution has become a serious problem, which justifies a very active quest for effective electromagnetic interferences (EMI) shielding materials. Polymers filled with carbon fillers have been widely investigated for EMI shielding purposes because of unique combination of electrical conductivity and polymer flexibility....
متن کاملElectromagnetic interference (EMI) shielding of single-walled carbon nanotube epoxy composites.
Single-walled carbon nanotube (SWNT)-polymer composites have been fabricated to evaluate the electromagnetic interference (EMI) shielding effectiveness (SE) of SWNTs. Our results indicate that SWNTs can be used as effective lightweight EMI shielding materials. Composites with greater than 20 dB shielding efficiency were obtained easily. EMI SE was tested in the frequency range of 10 MHz to 1.5 ...
متن کاملEffect of Carbon Nanotube and Surfactant on Processing, Mechanical, Electrical and EMI-Shielding of Epoxy Composites
Dispersing nanoparticles in a polymer matrix is intrinsically challenging due to unfavorable entropic interactions between the matrix and the nanoparticle. In this research dispersion of nanoparticles in polymer matrix was studied and the effect of dispersion on properties was investigated. The properties of polymer composite depend on the type, size, shape, concentration of nanoparticles, and ...
متن کاملShielding Effectiveness Simulation of Small Perforated Shielding Enclosures Using FEM
Numerical simulation of shielding effectiveness (SE) of a perforated shielding enclosure is carried out, using the finite element method (FEM). Possibilities of model definitions and differences between 2D and 3D models are discussed. An important part of any simulation is verification of the model results—here the simulation result are verified in terms of convergence of the model in dependenc...
