In the design of high Quality factor (Q) micro or nano beam resonators, different dissipation mechanisms may have damaging effects on the quality factor. One of the major dissipation mechanisms is the thermoelastic damping (TED) that needs an accurate consideration for prediction. In this paper, thermoelastic damping of the longitudinal vibration of a homogeneous micro beam with both ends clamp...

We design a novel nano-ring resonator using two-dimensional photonic crystal (2D-PhC), for bio-sensing applications. The structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. These are configured by removing one row of air holes. The refractive index of sensing hole is changed by binding an analyte. Hence, intensity of the transmission spectrum...

In this paper, chiral E-shaped resonators are used in a waveguide. Direction of EM wave and position of resonators for effective excitation is studied and various resonances of E-shaped resonators are determined. As a consequence an analytical equivalent circuit model is proposed. Finally, an array of these resonators is used to realize a wide reject band. The resulted band stop filter performa...

Quantum nano-structures are likely to become primary components of future electronic devices. Presently the majority of these structures, such as nano-mechanical resonators, semiconductor quantum dots, single electron transistors, and similar low dimensional structures, exist as prototypes in research laboratories or just being contemplated. Practical realization of quantum devices faces a numb...

Advances in nano-fabrication techniques has made it feasible to observe damping phenomena beyond the linear regime nano-mechanical systems. In this work, we report cubic non-linear palladium resonators. Nano-scale beams exposed a $H_2$ atmosphere become softer and display enhanced Duffing non-linearity as well at ultra low temperatures. The is highest lowest temperatures of $\sim 110\: mK$ decr...

We consider frequency fluctuations in self-sustained oscillators based on nonlinear underdamped resonators. An important type of such resonators are nano- and micro-electro-mechanical systems. Various noise sources considered, with the emphasis fundamentally unavoidable that comes along dissipation from coupling to a thermal reservoir. The formulation terms action-angle variables resonator allo...
