ELECT A new ultra-wideband (UWB) antenna integrated with a narrow-band (NB) antenna has been designed and fabricated. The UWB antenna consists of a U-shaped dielectric resonator fed by a microstrip line. In addition, the proposed structure integrates an NB slot with the same polarisation. The electromagnetic analysis is carried out by using two commercial software tools. To validate the propose...

Optical microresonators have proven powerful in a wide range of applications, including cavity quantum electrodynamics1-3, biosensing4, microfludics5, and cavity optomechanics6-8. Their performance depends critically on the exact distribution of optical energy, confined and shaped by the nanoscale device geometry. Near-field optical probes9 can image this distribution, but the physical probe ne...

This paper presents the analysis of a mechanical and theoretical model mi-cromechanical RL-type gyroscope (MMG). The behavior resonator in free oscil-lation mode is studied by solving problem linear formulation. main part devoted to mathematical development for dual-mass MMG with disk-shaped resonator, which fixed on elastic leg movable base. important condition implies arbitrary angular veloci...

A band-pass filter is a wireless component that transmits frequencies within certain range and attenuates outside range. Band-pass (BPF) has been used as core for an Radio Frequency (RF) communication system. BPF generally designed based on transmission line resonators. Therefore, miniaturization of these components important. In this study, triangle-shaped with meander-line resonator complemen...

A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular ra...

We present a detailed study of the generation photon pairs by spontaneous four-wave mixing in structure composed two linearly uncoupled resonators, where energy can be transferred from one resonator to another only through nonlinear interaction. Specifically, we consider case racetrack-shaped resonators connected coupler designed guarantee that resonance comb each tuned independently and allow ...
