Homogenization for Periodic Media & Complex Nanostructures (in Biophotonics)
Résumé
The mathematical tools for the up-scaling from nano, micro to macro in "periodic media" are considered in the use of multifaceted nano-objects with a special mention to in vivo biophotonics (functional imaging with femtosecond or continuous laser) where biological tissues are highly heterogeneous media at the nanoscopic, microscopic and macroscopic scales. The light absorption in a tissue with nano-objects could be modeled by the Helmholtz equation
