Paper Abstract

Multicontrollability is just beginning to emerge as an engineering paradigm. It is necessary for fault-tolerant operation because multiple agents become available to perform a specific function. This built-in redundancy promotes seamless operation in variable conditions. Inspired by biological multicontrollability, multicontrollable metasurfaces have been conceptualized for terahertz applications. Comprising electrically small elements called MetaAtoms made of diverse pixels each of which is variously controlled, a metasurface could be either homogeneous or graded on the wavelength scale. As an example, terahertz transmission of a normally incident plane wave through a metasurface with subwavelength MetaAtoms containing diverse pixels of magnetostatically controllable material (InAs) and thermally controllable material (CdTe) was analyzed. The co-polarized transmission coefficients were found to exhibit stopbands that shift by switching on/off the magnetostatic field and/or increasing/decreasing the temperature.
