A complex approach to the theoretical study of 3D-chiral plasmonic nanohole arrays is presented, including the reconstruction of a real structure shape using AFM data, full-scale FDTD simulation, and coupled-mode model approximation. Prospects of using metal-hole arrays for the enhanced optical detection of molecular chirality in nanosized volumes are investigated. The ambiguity of the macroscopic description of light pressure on a continuous medium is discussed, including the case of negative refraction. It is shown that, although there exists a continuum of formally correct formulations, one can adopt the appropriate form of the macroscopic field stress tensor that allows a unified description of pressure during elementary light-matter interactions, such as reflection, refraction, absorption.
