Abstract. Well-ordered metal structures, i.e. arrays of nanosized tips on silver surface for studies of the luminescence enhancement of absorbed media with rare earth ions were used. These arrays were prepared by the metal evaporation on track membranes. Calculations of resonance frequencies of tips regarded as semispheroids were done taking into account the interaction between dipoles of tips. Contemporary software for electrodynamics modeling can be applied to regard the mentioned above nanosized optical systems too. By using FDTD from CST Microwave Studio preliminary calculations for extinction cross section of silver tip arrays and other nanosized gold and silver metal structures have been performed. Distributions of the electromagnetic fields and different characteristics of the fields have been obtained.
Keywords: rare earth ions; silver nanosized tips; luminescence enhancement; optical amplifier; plasmon modes; numerical modelling of optical systems.
