A simulation model of the human body is developed in frequency dependent Crank Nicolson finite difference time domain (FD-CN-FDTD) method. Numerical simulation of electromagnetic wave propagation inside the human head is presented. Advantages of using time discretization beyond the Courant Friedrich-Lewy (CFL) limit in FD-CN-FDTD method are shown. Parallelization using Open Multi-Processing (Op...

Sub-wavelength plasmonic light trapping nanostructures are promising candidates for achieving enhanced broadband absorption in ultra-thin silicon (Si) solar cells. In this work, we use finite-difference time-domain (FDTD) simulations to demonstrate...

Abstract This structure proposes the creation of optical biosensor that can be used to detect vitiligo caused pigment loss. For accomplishing this, a pair 2-D photonic crystal structures, such as K3 and K7 resonators, are examined. The study both resonator structures is succeeded using (FDTD) Finite Difference Time Domain. Lumerical simulation tool model these in Domain (FDTD). subsequent prope...

The multiresolution time domain (MRTD) is used to analyze wide-band plane-wave scattering from general dielectric targets embedded in a lossy half-space, with free-space scattering as a special case. A Haar wavelet expansion is used for simplicity, this constituting a generalization of the widely used finite-difference time-domain (FDTD) method. In addition to developing the mathematical formul...

The traditional finite-difference time-domain (FDTD) method is constrained by the Courant–Friedrich–Levy condition and suffers from notorious staircase error in electromagnetic simulations. This article proposes a 3-D conformal locally one-dimensional FDTD (CLOD-FDTD) to address two issues for modeling perfectly electrical conducting (PEC) objects. By considering partially filled cells, propose...

The finite difference time domain (FDTD) method is commonly used as a numerically accurate way of propagating sound. However, it requires extensive computation. We present a simple method for accelerating FDTD. Specifically, we modify the FDTD update loop to prioritize computation where it is needed most in order to faithfully propagate waves through the simulated space. We estimate for each po...

The class of problems to which the Finite-Difference Time-Domain (FDTD) method can be applied is extended through the use of near and far-field projection techniques. These methods are developed by applying the equivalence principle to a surface within the FDTD problem space. Algorithms are found to project the equivalent electric and magnetic currents on this surface to any point in space eith...

The multiresolution time-domain (MRTD) algorithm is applied to the problem of general two-dimensional electromagnetic scattering. A Haar wavelet expansion is utilized. A parallel between Haar MRTD and the classic Yee finite difference time-domain (FDTD) algorithm is discussed, and results of simulations on canonical targets are shown for comparison. We focus on the incident-field implementation...
