PSTD Suite
Today, tissue optics is a very hot field with many new techniques being developed.
However, most research attempts are based on heuristic approximations, simply because a rigorous solution
Based on fundamental electromagnetic principles was not available,
I am presenting here the PSTD suite, capable of solving Maxwell’s equations for a large-scale light scattering problem by biological random media.
In my presentation, I will talk about the development of the PSTD suite (which took approximately two years to develop from scratch), and also talk about some research findings of specific projects.

3. Pseudospectral Time-domain Method
Grid-based simulation tool
Numerical realization of the Maxwell’s equations for arbitrary, macroscopic geometries
Virtual experiment with controllable variables in a noise-less environment
Today, the research tool I have presented opens up a whole new horizon for the research of tissue optics. By rigorously solving Maxwell’s equations, for the first time, tissue optics can be studied based upon fundamental electromagnetic theory, without heuristic approximations.
