O projektu

In the project we plan to study the effect of strong coupling between the localized surface plasmons in antennas and the excitations in their resonantly absorbing non-metallic environments and, consequently, to exploit this knowledge for finding and utilizing general principles of localized plasmon-enhanced absorption. We intend to tackle this problem in over a wide electromagnetic spectrum, ranging from the mid-IR rangeto the visible. However, Such a broader approach is possible due to common features of index of refraction at anomalous dispersion related to absorption peaks/bands of materials, the outcomes and conclusions can find direct applications in other spectral regions, regardless the physical origin of resonant absorption. We propose to go beyond the nowadays knowledge and limits on optimization of localized plasmon-enhanced absorption upon the strong coupling regime over a large spectral area. It will make it possible to carry out research on challenging phenomena exploitable not only in the local heating of materials, but also in IR and light detection, energy harves
