in this paper, a generalized method for accurate full-wave analysis of shielded mic's and the three-layer microstrip structure enclosed in a rectangular cavity based on mixed potential integral equation (mpie) derived in real space have been developed. method of moments (mom) with galerkin technique has been used for the solution of the integral equation to obtain the surface electric currents ...

The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...

With appropriate setup, shielded planar EM (electromagnetic) analysis can be used for antenna analysis. While shielded EM analysis can not handle the variety of antenna problems that unshielded analysis can, shielded analysis offers extreme numerical robustness. This robustness allows, in turn, rigorous identification, quantification, and elimination of analysis error sources. This robustness a...

Hybrid magnetic shields with both active field generating components and high-permeability shielding are increasingly needed for a variety of technologies experiments that require precision-controlled environments. However, the fields generated by interact passive shield, distorting desired profiles. Consequently, optimization to generate user-specified target must include coupling components. ...

“Open” magnetic resonance imaging (MRI) scanners are frequently based on electromagnets or permanent magnets, and require self-shielded planar gradient coils to prevent image artifacts resulting from eddy currents in metallic parts of the scanner. This work presents an optimization method for the development of self-shielded gradient coils with biplanar geometry for “Open” MRI scanners. Compare...
