Abstract: The present invention minimizes issues with transmission lines through the use of a normal-metal/superconducting meta-material structure realized with controlled impedance sub-wavelength line sections, which effectively concentrate the uncertainty in the section lengths in a portion of the termination geometry which has minimal impact on the non-resonant absorption in the structure. The present invention is used to achieve broadband absorption response and signal termination in planar transmission line devices. The longest wavelength sets the required length of the meta-material line, and its footprint is set by properties of the guiding structure (i.e., the resultant line can be folded, meandered, or spiraled with a spacing set is set by the field confinement of the transmission line topology in use).

Abstract: This disclosure covers methods, systems, and computer-readable media that generate a digital survey for respondents based on emotion attributes determined for the respondents from analyzed images of the respondents. In certain embodiments, by generating digital surveys by analyzing images for emotion attributes, the disclosed systems generate digital surveys that are customized for a respondent. To facilitate review of respondents' emotion attributes and the reliability of responses, in some embodiments, the disclosed systems further associate the emotion attributes with responses within a response database for the digital survey.
