In this letter, we report the infrared optical properties of a novel silica aerogel substrate. The properties were measured at room temperature using spectroscopic ellipsometry in the wavelength range from 8 to 14 μm. The measurements gave a refractive index in the range 1.01 to 1.09 and an extinction coefficient variation between approximately 0.0096 to 0.0104. These results confirm the effectiveness of using silica aerogel as a substrate for antenna-coupled microbolometer detectors..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
