FDTD-calculated field distributions in a metamaterial-core waveguide structure: soda-lime glass/(10-nm Ag/180-nm SiO2/10-nm Ag)/soda-lime glass. a Field amplitude distributions of H z , E x and E y for y in the range of − 2 to 2 µm. Note the log scale of field amplitude. b A close-up view of core layer part (10-nm Ag/180-nm SiO2/10-nm Ag). Note that normal E-field (green) takes different signs in metal and dielectric layers
