Near-Field and Far-Field Thermal Emission of Individual Subwavelength-Sized Resonators

We propose a modulation method to record background-free far field FTIR spectra of single sub -\lambda sized objects which we combine with near-field TRSTM measurements to characterize the thermal emission of plasmonic antennas and silica rods. The fundamental mode of MIM nanoantennas is excited at...

Summary:We propose a modulation method to record background-free far field FTIR spectra of single sub -\lambda sized objects which we combine with near-field TRSTM measurements to characterize the thermal emission of plasmonic antennas and silica rods. The fundamental mode of MIM nanoantennas is excited at multiple wavelengths. © 2019 The Author(s)
