The optimization have been performed using FDTD Solution simulation. Unit cell of perfect silver particles array on top of Si layer were investigated. The absorption was calculated from the transmission monitors located at the Si surface and at the depth of 0,5 um. The changing parameters were NPs size and sufrace coverage. The determined optimal structre should contain 140 nm particles covering 10 % of the surface. Additional cases of 15 nm SiO2 spacing layer and canche in the integration range in Am 1.5 spectrum were analyzed as well. Next step was experimental approach to this optimal structures.

December was another month that was dominated by
writing subsequent chapters of my dissertation.
At the end of the month, the first draft
of the dissertation was ready.

Correction of PhD draft. Improvement of one's own program for surface tension modelling.
Development NJ programs for ternanry system.

This year December was not a white but a bloody red month due to hemocompatibility evaluation of PEMs modified by SiC nanoparticles. All tests in the accompaniment of Christmas carols could be listen from the radio in the background were performed on the home-made devices such as the aortic flow simulator or artificial patient model.

FDTD Simulation set up was rearranged in order to obtian optimal simualtion conditions. Simualtion of low index materials like silver reiured very fine mesh and careful parameter adjustement. It was done by convergence testing and camparison of simulated and theoretical results of extinction cross section of Johnsnon and Cristy model. Next conidtions were veryfied for other models of silver. The most appropriate model was defined by adusting extinction plot with measured absrobance curve of actual suspension. Palik model seemed to provide the best match. It was used for further investigations.

Model suspension of 100 nm higly neagative particles was used to study the influance of PAH adsorption. The optimal conditions of ionic strength of 0,15 and pH 7 were found.
