Dielectric resonances in disordered media
Binary disordered systems are usually obtained by mixing two ingredients in variable proportions: conductor and insulator, or conductor and super-conductor. They present very specific properties, in particular the second-order percolation phase transition, with its fractal geometry and the multi-fractal properties of the current moments. These systems are naturally modeled by regular bi-dimensi...
متن کاملDielectric Materials in Magnetic Resonance
High permittivity materials find extensive use in high frequency communications devices due to their small size (compared to lumped element circuits), low losses and physical robustness. Recently, these types of materials have been applied in high field magnetic resonance imaging, based upon earlier work in electron paramagnetic resonance. This review article describes the basic properties of h...

Dielectric Resonance in Ultra High Field MRI
INTRODUCTION Since the start of magnetic resonance imaging, there has been a constant drive towards more powerful magnets and consequently higher operational frequencies. For head imaging, it is expected for the electromagnetic fields to be influenced by the presence of the tissue at these frequencies (field strength AT). As a result, fundamental problems were anticipated regarding the presence...
