Analysis of a thin-metal-core waveguide structure with symmetric dielectric cladding: silica (Q) or soda-lime glass (G). a Analytical calculation of propagation length for metal core (Ag) thickness in the range of 10–250 nm. b Analytical calculation of penetration depth into cladding. c FDTD simulation of field distributions in SiO2/10-nm Ag/SiO2 structure: log-scale plot of field amplitudes of H z , E x and E y for y in the range of − 2 to 2 µm. d A close-up view of field distributions around the 10-nm Ag core
