ENHANCED RADIATION PATTERNS OF A WIDE-BAND STRIP-FED DIELECTRIC RESONATOR ANTENNA [PDF]
A simple wide-band rectangular dielectric resonator antenna (DRA) is designed for the X-band and Ku-band applications. The DRA is excited by a vertical strip placed on the middle of the DRA wide side wall through a coaxial probe attached to a finite size

Circularly Polarized Dielectric Resonator Antenna With Two Annular Vias
In this paper, a new technique for circular polarization in a slot coupled dielectric resonator antenna is proposed. The circular polarization is generated by inserting the two annular vias into dielectric resonator slightly off the diagonal position. In

Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
