in this paper, the stability of a functionally graded magneto-electro-elastic (fg-mee) micro-beam under actuation of electrostatic pressure is studied. for this purpose euler-bernoulli beam theory and constitutive relations for magneto-electro-elastic (mee) materials have been used. we have supposed that material properties vary exponentially along the thickness direction of the micro-beam. gov...

In this Letter, we propose and demonstrate a high-speed and power-efficient thermo-optic switch using an adiabatic bend with a directly integrated silicon heater to minimize the heat capacity and therein maximize the performance of the thermo-optic switch. A rapid, τ=2.4 μs thermal time constant and a low electrical power consumption of P(π)=12.7 mW/π-phase shift were demonstrated representing ...

Cu as nearly immiscible components. However, it is well-known that in nanoscale structures the higher contribution of the interfacial energy to the thermodynamic potential can lead to a completely different phase diagram [1]. On the other hand, the electrical conductivity of nanoscale ferromagnetic multilayers separated by nonmagnetic interlayers strongly depends on the magnetic alignment betwe...

We demonstrate electrically driven nonreciprocity on a silicon chip. By achieving an indirect interband photonic transition, we show that the transmission coefficients between two single-mode waveguides become dependent on the propagation directions only in the presence of the electrical drive. Our structure is characterized by a nonsymmetric scattering matrix identical to a linear magneto-opti...

Recently, among other smart and multifunctional materials, magneto-electric soft materials are expected to open a new horizon with myriad of potential applications such as wireless energy harvesting, spintronics nonvolatile memories, random access memory, mention few. Magneto-electric coupling can be defined the ability material electrically polarize upon application magnetic field conversely, ...

The lifetime of micro electro–thermo–mechanical actuators with complex electro–thermo–mechanical coupling mechanisms can be decreased significantly due to unexpected failure events. Even more serious is the fact that various failures are tightly coupled due to micro-size and multi-physics effects. Interrelation between performance and potential failures should be established to predict reliabil...

In this paper we present optical and thermo-optical characterization results of integrated filters based on micro-ring resonators fabricated with a couple of polymers ‘‘PVCI/PMATRIFE’’. Their high index contrast (Dn 0.15 at the wavelength of 1550 nm) allows to make small size waveguides with cross sections of 1.5 1.5 mm2. The study of the impact of different gaps on the extinction ratio and FWH...

Modern automobiles incorporate more actuators, heaters, and other electrical loads than have automobiles in the past. This proliferation of high current, high power loads is presently challenging the longstanding assumption that the entire chassis will remain at one potential under a variety of different operating conditions. New voltage standards, alternator designs, and power electronics ensu...
