| contents | The optical response of mesoscale metallic nanostructures (MMNSs) with feature sizes down to extreme nanometer scales is largely affected by the nonclassical quantum effects, which can be comprehensively described by the nonclassical electromagnetic boundary condition (NEBC) incorporating surface-response Feibelman d-parameters. Here we report the Fourier modal method (FMM) and the coordinate transformation method (C method) under the NEBC, which are built up by incorporating the NEBC into a recently reported 3D-C method [Opt. Express 29, 1516 (2021)] that is applicable to the general three-dimensional (3D) photonic structures with curved boundaries. The validity and accuracy of the proposed method are confirmed numerically through a comparison with other full-wave method incorporating the NEBC. The present work marries the NEBC and the well-developed modal methods of FMM and C method, thus bringing the advantages of these modal methods in physical intuitiveness and computational efficiency to the electromagnetic modeling of nonclassical quantum effects in the MMNSs. |
