A metamaterial unit cell with a low refractive index over a wide frequency band is proposed and designed. The effective material parameters of the unit cell are extracted, and the unit cell forms a… Expand
Efficient Finite-Difference Time-Domain Modeling of Driven Periodic Structures and Related Microwave Circuit Applications
The sine-cosine method for the finite-difference time-domain-based dispersion analysis of periodic structures is extended to incorporate the presence of nonperiodic wideband sources. A new… Expand
Simultaneous localization and mapping embedded with particle filter algorithm
In this paper, a novel methodology is proposed to solve the simultaneous localization and mapping (SLAM) problem of mobile robot with particle filter (PF) algorithm. Compared with Kalman filter (KF)… Expand
A New Approach for the FDTD Modeling of Antennas Over Periodic Structures
A new approach is proposed for the time-domain modeling of antennas over periodic substrates. This class of problems would typically require a time-consuming simulation of the antenna structure with… Expand
Graphene-controlled fiber Bragg grating and enabled optical bistability.
We report a graphene-assisted all-optical control of a fiber Bragg grating (FBG), which enables in-fiber optical bistability and switching. With an optical pump, a micro-FBG wrapped by graphene… Expand
Adsorption of dibutyl phthalate in aqueous solution by mesoporous calcium silicate grafted non-woven polypropylene
Abstract The purpose of this research is to synthesize mesoporous calcium silicate grafted non-woven polypropylene (PP-g-CaSiO3@SiO2) and to evaluate its adsorption performance for dibutyl phthalate… Expand
Electromagnetic optimisation using sensitivity analysis in the frequency domain
Gradient-based optimisation relies on the response Jacobian whose evaluation constitutes a major computational overhead in full-wave numerical analysis. Adjoint-based techniques may offer numerically… Expand
A lower ALC/AMC ratio is associated with poor prognosis of peripheral T-cell lymphoma-not otherwise specified.
Peripheral T-cell lymphomas-not otherwise specified (PTCL-NOS) generally have poor patient outcomes, with a 5-year survival rate of ∼32%. The most common prognostic system for patients with PTCL-NOS,… Expand
Impedance calculation and equivalent circuits for metal-insulator-metal plasmonic waveguide geometries.
This Letter presents an analytical expression for the equivalent impedance of the fundamental mode of both 2D and 3D metal-insulator-metal (MIM) plasmonic waveguides. It also presents circuit models… Expand
Efficient finite-difference time-domain modeling of driven periodic structures
The paper proposes an efficient method to analyze the response of periodic structures to non-periodic excitations in the time domain, employing the finite-difference time-domain (FDTD) method. To… Expand
