In this work, a selective solar absorber made of nanostructured titanium gratings deposited on an ultrathin MgF[subscript 2] spacer and a tungsten ground film is proposed and experimentally demonstrated. Normal absorptance of the fabricated solar absorber is characterized to be higher than 0.9 in the UV, visible and, near infrared (IR) regime, while the mid-IR emittance is around 0.2.
