In this paper, we discuss simulation of one-port Surface Acoustic Wave (SAW) resonators using COMSOL Multiphysics. Resonator action can be achieved in one of the two ways; a single Inter-digital Transducer (IDT) having several fingers over a piezoelectric substrate or a short IDT with reflecting gratings at the ends of the IDT. We have modeled a Rayleigh wave type SAW device choosing YZ ...

This work is concerned with systems possessing cyclic symmetries. In particular, we concentrate on the case in which the medium possesses infinite order cyclic symmetry, while the constitutive relations have cyclic symmetry of a lower order. We investigate the interactions between modes with cyclic symmetry of order n and geometries with underlying cyclic symmetry of order M. Rayleigh's ...

Moving nanowires through microfluidic channels under electrokinetic forces can be a valuable technique to aid in the fabrication of certain devices. The trajectories of a nanowire under the influence of an externally applied electric field have been modelled through a straight channel, through a converging channel, and around a 90° corner. In a straight channel, a nanowire initially ...

The use of optical sensors in the industry is still growing. A transmission of signal from the sensors is mostly done by optical fibers. Switching the signals from optical paths may be done by using micromechanical silicon switches. The main advantage is an ability to transmit data from many sensors using different wavelengths, simultaneously minimizing optical power losses. A silicon beam with ...

Integration of surface acoustic wave (SAW) devices with nanostructures has gained interest in the development of sensors with high sensitivity. To better design nanostructure integrated SAW devices, it is essential to model three dimensional (3-D) SAW devices and analyze the wave propagation characteristics in nanostructure-enhanced SAW devices. In this work, a 3-D finite element model of ...

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we use ...

The newly emerging field of carbon-based MEMS (C-MEMS) attempts to utilize the diverse properties of carbon to push the performance of MEMS devices beyond what is currently achievable. Our design employs a carbon-carbon composite using nano-materials to build a new class of MEMS accelerometer that is hyper-sensitive over a dynamic range from micro-G to hundreds of G’s – far surpassing the ...

The microscopic size of MEMS devices accounts for strong coupling effects which arise between the different physical fields and forces. Micromirrors are essential parts of microswitches in fiber optic network telecommunication. They are usually 1 to 3 mm in size, fabricated from single crystalline silicon and mostly are electrostatically actuated. The objective is to design the micromirror to ...
