Abstract Microelectromechanical systems (MEMS) based ring shaped resonators usually have a supported by spoke springs. In this paper, we developed general analytical model that can determine the natural frequency of any MEMS resonator considering effective mass and stiffness spokes in both radial tangential displacements. Our is also able to circular curved beam with arbitrary central angle. Th...
Abstract Metasurfaces have attracted widespread interest owing to their ability control light at the nanoscale level. However, optical response of dipole mode-based metasurfaces is sensitive changes in resonator period and incidence angle; thus, device performance typically degrades practical applications presence non-normal incident light. Here, we study cross-shaped Mie resonators based on qu...
In this paper, a wideband Sierpinski carpet patterned cylindrical Dielectric Resonator Antenna (DRA) operating in the X-Band is proposed. This DRA is realized from low cost Teflon. An impedance bandwidth of 50% is obtained covering the entire X-band with similar radiation pattern throughout the band. The average peak gain within the band is about 5.5 dBi.
