In this paper, a 1D photonic crystal waveguide and plasmonic compound nano-system are utilized to design hybrid photonic-plasmonic device for enhancement of light–matter interaction. Strongly localized light waves in very small volume intensify the optical field, via surface plasmons due presence gold nanoparticle, which interacts with resonator’s cavity mode while nanobeam ensures high tempora...

In this paper, we use single negative metamaterials to reduce the electromagnetic interaction between the mobile phone and human head. The specific absorption rate (SAR) in the head can be reduced by placing the metamaterials between the antenna and the head. We design the single negative metamaterials from periodic arrangement of split ring resonators (SRRs), spiral resonators (SRs) and open s...

This paper describes the design and analysis of planar dualband bandpass filters using stepped impedance resonators. In the proposed filter configurations, dual-band bandpass filters are designed, and realized by using inverted stepped impedance (SIR) resonators. The conventional half wavelength open circuited stub single frequency resonators are replaced with dual band simple two section stepp...

This paper, the second of two parts, introduces electrostatic coupling of micromechanical resonators for implementation of high-order narrow-bandwidth bandpass filters. The concept of electrostatic coupling of closely spaced microresonators and its electromechanical modeling is presented. Electrostatic coupling of resonators does not require any distinct physical coupling elements. The electros...

We report the observation of optically pumped lasing in self-coupled resonators constructed with dye-doped polymer nanowires. Three nanowires with a diameter of 350 nm, 360 nm and 500 nm were fabricated into different self-coupled resonators and single-mode lasing emission was obtained. The self-coupled resonators can be utilized to realize tunable laser systems and enhance the coupling efficie...

We propose a quantum computing architecture based on the integration of nanomechanical resonators with Josephson-junction phase qubits. The resonators are GHz-frequency, dilatational disk resonators, which couple to the junctions through a piezoelectric interaction. The system is analogous to a collection of tunable few-level atoms (the Josephson junctions) coupled to one or more electromagneti...

In this paper, we have designed a metasurface based on electrically tunable Mie-type resonators and theoretically demonstrated its tunable response to electromagnetic waves with varying frequency. The metasurface consists of disk-like ferroelectric resonators arrayed on a metal film and the upper surface of resonators is covered by ion gel film which is transparent for incident electromagnetic ...

Microelectromechanical resonators are advantageous over traditional LC tanks and off-chip quartz crystals due to their high quality factors, small size and low power consumption. FET-sensing has been demonstrated in resonant body transistors (RBTs) to reach an order of magnitude higher frequencies than possible with passive resonators due to the greater sensing efficiency of FET sensing over tr...
