Electromagnetic Characterization of Shielded Spherical Gyromagnetic Resonators

Software for Design NMR Probes Using the Shielded Split Ring and the Shielded Symmetrical Band Resonators

This article presents a software (NMR PROBES) for design NMR probes using closed-forms formulas of the primary and secondary parameters of the shielded split ring [1] and the shielded symmetrical band resonators [2]. These formulas are based on rigorous analysis by finite element method (FEM) [3], [4], method of moment (MoM) [5] and curves fitting techniques. The presented software permits the ...

3-d Micromachined Spherical Shell Resonators with Integrated Electromagnetic and Electrostatic Transducers

(a) Before glassblowing (b) After glassblowing Figure 2: Photographs of fabricated 3-D spherical shell resonators with integrated electrostatic transducers. This paper presents a new paradigm for design and fabrication of 3-D spherical shell resonators. The approach uses pressure and surface tension driven plastic deformation (glassblowing) on a wafer scale as a mechanism for creation of inhere...

Symmetric and antisymmetric modes of electromagnetic resonators

In this paper, we numerically study a new type of infrared resonator structure, whose unit cell consists of paired split-ring resonators (SRRs). At different resonant frequencies, the magnetic dipoles induced from the two SRRs within one unit cell can be parallel or antiparallel, which are defined as symmetric and antisymmetic modes, respectively. Detailed simulation indicates that the symmetri...

Electromagnetic Waves Propagation and Detection in Shielded Dielectric Power Cables

Partial discharge occurs a lot in shielded dielectric power cables. Partial discharge pulses are high-frequency electromagnetic waves that propagate in the shielded dielectric power cables. This chapter will study partial discharge propagation and detection in shielded dielectric power cables.
