Abstract

Dielectric resonators with Ultra-High Dielectric Constant (uHDC) materials possess intrinsic resonance modes which can be employed in the design of transceiver coils for magnetic resonance imaging (MRI) applications. The resonance modes and conditions of the uHDC discs were studied through computer simulations. We compared the magnetic field and Rx-sensitivity when employing cylindrical uHDC discs at both resonant and non-resonant conditions. We showed in this work, to achieve the maximum focusing of the magnetic field into the phantom, the design with uHDC material should operate around the first TE01δ mode and lower than the second mode with the highest permittivity.
