Abstract A phononic-fluidic cavity sensor is a new type of acoustic fluid to measure volumetric liquid properties. In our work, it consists solid-air 3D phononic crystal (PnC) layers confining fluidic resonator generate strong, well separated resonance within the band gap. This allows for measurement changes in speed sound analyte with very high, linear sensitivity. this we present theoretical ...

We theoretically present a design of self-starting operation microcombs based on laser-cavity solitons in system composed micro-resonator nested and coupled to an amplifying laser cavity. demonstrate that it is possible engineer the modulational-instability gain system’s zero state allow start-up with well-defined number robust solitons. The approach can be implemented by using parameters, such...

we propose a new ring resonator side-coupled m-z interferometer all-optical switch throughthe pumped nonlinear directional coupler. by controlling pump power p to lead the coupler reflectivityr approaching to 1, the resonator finesse will be enhanced dramatically, and then the minimumswitching power in silica-based practice devices can be obtained. as a sample, we use a nonlinearcoupler made by...

Space-filling approach, such as a series of TreeMaps algorithms, is one of the popular approaches in hierarchical data visualization. The original TreeMaps [1] represents the hierarchy as nested belt chart (so called slice-and-dice), and then it has been improved by squarifying or ordering the subregions representing the nodes of a tree. These algorithms represent quantitative properties of nod...

The fields of cavity quantum electrodynamics and magnetism have recently merged into spintronics, investigating a quasiparticle that emerges from the strong coupling between standing electromagnetic waves confined in microwave resonator quanta spin waves, magnons. This phenomenon is now expected to be employed variety devices for applications ranging communication dark matter detection. To succ...

Tiling is a crucial loop transformation for generating high performance code on modern architectures. Efficient generation of multi-level tiled code is essential for maximizing data reuse in systems with deep memory hierarchies. Tiled loops with parametric tile sizes (not compile-time constants) facilitate runtime feedback and dynamic optimizations used in iterative compilation and automatic tu...

abstract background: given the fact of irrecoverable consequences of noise in industrial societies and the environment, acoustic filter (silencer) is an instrument which obstacles the transmission of sound waves. a sort of this silencer is helmholtz resonator (branch amplifier) which comes to sound appropriate for low and below 200 hz frequencies in fan and channel noise. the purpose of this ar...

This work focuses on a compact circularly polarized wideband rectangular dielectric resonator antenna (RDRA) for X-band wireless applications. The response of the RDRA is initially generated by coaxial probe, RDR, an air gap in DR and slot shape ground. circular polarization achieved via incorporation unique feeding mechanism. edge with probe generates orthogonal modes that make design circular...

In this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. The shape of ring resonator filter adding and dropping that wehave proposed is Race Track. This filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. Transmissionefficien...
