Finite-Difference Time-Domain (FDTD) Simulator
This simulation package, which implements the FDTD algorithm on
a nonuniform mesh, is designed to run as a stand-alone program
as well as in conjunction with DIFFRACT™.
The interface with DIFFRACT™ makes it especially powerful
for simulations that involve near-field interactions with subwavelength
structures as well as propagation through complex optical systems.
For example, in Optical Data Storage applications, Sim3D_Max enables
the user to move beyond the limitations of DIFFRACT™ in
resolving reflection from, or transmission through, nano-scale
size objects such as grooves, pits, and bumps on an optical disk
surface. Sim3D_Max™ can take as its input the vector field
generated by DIFFRACT™ (fully propagated from the laser
diode to the surface of the optical disk), and returns to DIFFRACT™
the back-reflected beam for further propagation in the return
path, all the way to the photodetectors.
is a computationally intensive code that can run in parallel and take advantage of multiple
processors in a multi-core, multi-cpu workstation or a network cluster of such workstations
running Windows operating system. Sim3D_Max supports
clusters of Windows™ NT,2000 and XP workstations as well as
Microsoft™ Windows Compute Cluster Server based High Performance systems
that use MS MPI™.
In addition, Sim3D_Max™ is also available with the Acceleware™ hardware acceleration
option that allows for a several fold improvement in the computation speed for desktop systems.
The powerful interface to DIFFRACT™
notwithstanding, Sim3D_Max™ is a stand-alone simulation
package, complete with its own integrated Graphical User Interface
(GUI). All graphical and analysis functionality is carried out
within this GUI environment. For examples of simulations by Sim3D_Max™,
please see on-line publications "Interaction of Light with
Subwavelength Structures," and "Transmission of Light
Through Small Elliptical Apertures, Parts 1 and 2."
