This article describes an algorithm for calculating the relative permittivity from a stepped frequency continuous wave radar (SFCW) signal. The intended application for the developed radar is a quality estimation of the road surface layer, which incl

Noble metal nanoparticles, silver and gold nanoparticles as examples, can support localized surface plasmon resonances (LSPR), i.e., collective oscillations of surface-charge density upon excitation with, for example, light. The resonant character of
