Analysis of a hemispherical dielectric resonator antenna with an airgap

IEEE Microwave and Guided Wave Letters, 1993
A probe-fed hemispherical dielectric resonator antenna with an airgap of hemispherical shape between the dielectric and the ground plane is investigated theoretically by using a Green's function formulation. Input impedance of the efficiently radiating mode of TE/sub 111/ is calculated and analyzed.

Balancing of hemispherical resonator gyros by chemical etching

Gyroscopy and Navigation, 2015
A procedure for balancing the four lower harmonics of the mass distribution defect in a fused quartz hemispherical toothless resonator of a hemispherical resonator gyroscope is considered. Chemical etching of unbalanced mass from the surface of a partially immersed resonator is done in accordance with analytically calculated angle of the resonator ...

Finite-difference analysis of a loaded hemispherical resonator

IEEE Transactions on Microwave Theory and Techniques, 2003
A rotationally symmetric inhomogeneously loaded open hemispherical resonator is analyzed using the finite-difference (FD) frequency-domain method. State-of-the art or new techniques are proposed to achieve high accuracy and efficiency of computations. These include applying the Galerkin method followed by an inexact shift-and-inverse Lanczos technique ...

Micromachined polycrystalline diamond hemispherical shell resonators

2013 Transducers & Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS & EUROSENSORS XXVII), 2013
The hemispherical resonator gyro (HRG) is low loss and high stability, spurring recent interest in micro-scale hemispherical resonators. To achieve mode-matching and high-Q performance in a hemispherical resonator, geometric symmetry in combination with low thermoelastic damping structural material are critical.
