Brownian motion of arbitrarily shaped particles in two dimensions.
We implement microfabricated boomerang particles with unequal arm lengths as a model for nonsymmetric particles and study their Brownian motion in a quasi-two-dimensional geometry by using high-precision single-particle motion tracking. We show that because of the coupling between translation and rotation, the mean squared displacements of a single asymmetric boomerang particle exhibit a nonlin...
متن کاملTwo-curve-shaped biosensor using photonic crystal nano-ring resonators
We design a novel nano-ring resonator using two-dimensional photonic crystal (2D-PhC), for bio-sensing applications. The structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. These are configured by removing one row of air holes. The refractive index of sensing hole is changed by binding an analyte. Hence, intensity of the transmission spectrum...
متن کاملDispersion engineering of photonic crystal waveguides with ring-shaped holes.
The geometry of photonic crystal waveguides with ring-shaped holes is optimized to minimize dispersion in the slow light regime. We found geometries with a nearly constant group index in excess of 20 over a wavelength range of 8 nm. The origin of the low dispersion is related to the widening of the propagating mode close to the lower band gap edge.
متن کاملAn Economic Method for the Solution of the Scalar Wave Equation for Arbitrarily Shaped Optical Waveguides
In the method presented here, the discrete sine method, the basis functions consist of sine functions defined on a set of parallel discretization lines. The method is a combination of a scalar version of the finite difference method and the sine method. The choice of the basis set leads, for the eigenvalue equation to be solved, to a sparse matrix with a small bandwidth. As a consequence, the p...
متن کاملMultiple-scattering theory for two-dimensional arbitrarily shaped acoustic composites
Multi-scattering theory (MST) is an analytical tool which allows for the resolution of the field dispersed (scattered) by an interfering medium after leaving a source. The basis of the method consists in determining the way each inhomogeneity (scatterer) in the medium affects the incident wave, something which ultimately depends on the shape and mechanical properties of the scatterer. Unlike pr...
