Very small electromechanical coupling coefficient in micro-electromechanical systems (MEMS) or acoustic resonators is quite a concern for oscillator performance, specially at mmWave frequencies. This the manifestation of ratio motional capacitance to static resonators. work provides general solution overcome problem relatively high frequencies and presents analysis design techniques achieving e...

The inability of Moore’s Law and other figure-of-merits (FOMs) to accurately explain the technology development of the semiconductor industry demands a holistic merit to guide the industry. Here we introduce a FOM termed CLEAR that accurately postdicts technology developments since the 1940’s until today, and predicts photonics as a logical extension to keep-up the pace of information-handling ...

The design of unit cell metamaterial can tailor the permittivity and permeability. negative refractive index was achieved while real part permeability simultaneously or ? r ? i + < 0 conditions were satisfied, where , are permittivity, imaginary permeability, respectively. Currently, based on paper is a fascinating issue. Additional, used as dielectric due to its eco-friendly spacer. critical r...

Abstract The sensing performance of a bimetallic core-shell nanotube is studied theoretically based on the theory TE-polarized light scattering by multilayer infinite cylinder. consists metallic core and shell with analyte inserted between shell. It found that absorption efficiency spectra exhibit three resonance peaks correspond to dipole, quadrupole sextupole mode. As refractive index increas...
