Proof of principle Optical rectenna

-


figure 5. experimental , theoretical emissivity function of wavelength. experimental spectrum determined heating optical antenna 200 °c , comparing spectral radiance blackbody emission @ 200 °c.


after proof of concept on stiff silicon substrate, experiment replicated on flexible polymer-based substrate. target wavelength flexible substrate set 10 µm. initial tests show antenna design can translated polymer substrate, further experiments needed optimize characteristics.


the proof of principle of optical antennas can realized in radio frequency range. high permittivity dielectric particles can used simulate silicon behaviour @ optical frequencies. allows perform experiment @ microwave in order predict antenna behavior @ optics.
