FDTD simulation results for NDA and MHA structures endowed with SiO2 insulator layers. Reflectance as well as extinction, scattering and absorption cross-section spectra are depicted in top plots, whereas x − y and x − z plane field intensity profile illustrations for both structures at resonance are given below. Incident radiation electric field was linearly polarized as marked by arrows.
