SAW Parameters Analysis and Equivalent Circuit of SAW Device

Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the intr...

Experiment and Simulation Validated Analytical Equivalent Circuit Model for Piezoelectric Micro-Machined Ultrasonic Transducer

An analytical Mason equivalent circuit is derived for a circular, clamped plate piezoelectric micro-machined ultrasonic transducer (pMUT) design in 31 mode considering an arbitrary electrode configuration at any axisymmetric vibration mode. The explicit definition of lumped parameters based entirely on geometry, material properties and defined constants enables straightforward and wide ranging ...

Analysis and modeling of Fano resonances using equivalent circuit elements

Fano resonance presents an asymmetric line shape formed by an interference of a continuum coupled with a discrete autoionized state. In this paper, we show several simple circuits for Fano resonances from the stable-input impedance mechanism, where the elements consisting of inductors and capacitors are formulated for various resonant modes, and the resistor represents the damping of the oscill...

mathematical modelling of multi winding transiofmer and its equivalent circuit

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...
