ADI-FDTD Modeling of Tellegen Media

Unified Efficient Fundamental Adi-fdtd Schemes for Lossy Media

This paper presents the unified efficient fundamental alternating-direction-implicit finite-difference time-domain (ADIFDTD) schemes for lossy media. The schemes presented include averaging, forward-forward, forward-backward and novel exponential time differencing schemes. Unifications of these schemes in both conventional and efficient fundamental forms of source-incorporated ADIFDTD are provi...

Unconditionally Stable Leapfrog Adi-fdtd Method for Lossy Media

This paper presents an unconditionally stable leapfrog alternating-direction-implicit finite-difference time-domain (ADIFDTD) method for lossy media. Conductivity terms of lossy media are incorporated into the leapfrog ADI-FDTD method in an analogous manner as the conventional explicit FDTD method since the leapfrog ADI-FDTD method is a perturbation of the conventional explicit FDTD method. Imp...

Modeling hemoglobin at optical frequency using the unconditionally stable fundamental ADI-FDTD method

This paper presents the modeling of hemoglobin at optical frequency (250 nm - 1000 nm) using the unconditionally stable fundamental alternating-direction-implicit finite-difference time-domain (FADI-FDTD) method. An accurate model based on complex conjugate pole-residue pairs is proposed to model the complex permittivity of hemoglobin at optical frequency. Two hemoglobin concentrations at 15 g/...

Development of an Fdtd Tool for Modeling of Dispersive Media

Parallelisation of Implicit Time Domain Methods: Progress with ADI-FDTD

We provide an overview of our work to date on the parallelization of implicit time domain methods, in particular the alternating direction implicit finite-difference time-domain method (ADI-FDTD). First we describe a domain decomposition scheme for parallel ADI-FDTD in three dimensions that is suitable for implementation on widely available high performance computer architectures such as symmet...
