'This free offering gives academic organizations, research institutions, and corporations throughout the world the ability to simulate their FDTD projects regardless of budget'. 'Using our free FDTD software, users can design a multitude of applications including: Surface Plasmon Resonance (SPR), photonic band gap devices, nanoparticles, diffractive micro-optic elements, complex integrated optical structures, optical micro-ring filters, grating based waveguide structures, and electro-magnetic phenomena' said Jan Jakubczyk, President and CEO of Optiwave. This allows for arbitrary model geometries and places no restriction on the material properties of the devices. The algorithm solves both electric and magnetic fields in temporal and spatial domain using the full-vector differential form of Maxwell's coupled curl equations. The core program of OptiFDTD is based on the Finite-Difference Time-Domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary conditions - Uniaxial Perfectly Matched Layer (UPML). OptiFDTD freeware enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena. This freeware includes the complete set of OptiFDTD features, requires no licensing dongle, and operates perpetually. Free Download Manager makes downloading files and videos easier and faster and helps avoid dreaded broken downloads. Optiwave has been successfully developing FDTD software for over a decade, and would like to show appreciation to the photonics community by distributing its 32-bit FDTD product at no cost. OTTAWA, ONTARIO-(Marketwired - Feb 25, 2014) - Optiwave Systems Inc., the leading provider of optical component and system design tools, today announced the immediate availability of its free OptiFDTD 32-bit software.
