Web5 de out. de 2009 · For the lossy case simulation, I assigned the lossy material properties to the radiation box. Again, I'm using radiation boundary conditions and the lambda/4 dimension spec. I checked for convergence. However, the results that I obtain do not make sense. For example, the gain vs. freq plot depends on the size of the radiation box. Web7 de jan. de 2024 · First, the magnetic material does impact the measurable E field value and, thus, attenuation level. Second, having a metal layer does help attenuate the EMI noise whether it’s with ferrite or permalloy magnetic material. Finally, being able to ground the shield further improves the shielding performance. ppt for formal presentation https://jjkmail.net
