| Description
| - Today, the techniques based on the phenomenon of surface-enhanced Raman scattering (SERS) has been finding many interesting applications. Although not fully understood yet, prevailing explanation takes account of electromagnetic and chemical contributions to Raman scattering %22amplification%22, with the enhancement factor spanning several orders of magnitude, when molecules under investigation are adsorbed on metal nanoparticles or more complex nanostructured metal surfaces (called SERS-active substrates). Two main requirements for high-quality SERS substrates include large enhancement factors (mainly in small regions called hot spots) and homogeneity of substrates. Concerning possible morphology and design of SERS structures, there are several design strategies available, with the experimental technique, based on selfassembly approaches, belonging to the most progressive ones. Recently, in our department, the experimental techniques and preparation procedures based on the bottom-up approach using self-assembly technique have been mastered and successfully applied to periodic SERS substrate preparation. In this way, series of various reproducible periodic arrays of semishells, nanobowls, and other types of substrates have been prepared, characterized, and tested under SERS measurements in recent years. These structures are indeed one of good candidates for %22best%22 SERS-active substrates. Concerning the complexity and rich physics of such structures, advanced numerical electromagnetic techniques are required for reliable numerical studies and predictions of structural behavior. Such detailed simulations, helping to understand the undergoing physics, have not mostly been available yet. Hence, in this contribution, we present our recent studies on the electromagnetic modeling of two promising types of advanced SERS substrates with the rigorous 3D finite difference time domain (FDTD) technique.
