The responsivity of these types of antennas is evaluated from both theoretical and numerical perspectives pointing out its potential as infrared sensors. Moreover, the same structures can be used to characterize the state of polarization of the optical near fields with a spatial resolution comparable to the wavelength. 1094-4087 10.1364/OE.22.0A1538 https://hdl.handle.net/20.500.14352/33991 http://dx.doi.org/10.1364/OE.22.0A1538 http://www.opticsinfobase.org/oe/abstract.cfm?URI=oe-22-S6-A1538 Seebeck nanoantennas for the detection and characterization of infrared radiation
