A promising ultra-sensitive CO₂ sensor at varying concentrations and temperatures based on Fano resonance phenomenon in different 1D phononic crystal designs.

ABSTRACT: Detecting of the levels of greenhouse gases in the air with high precision and low cost is a very urgent demand for environmental protection. Phononic crystals (PnCs) represent a novel sensor technology, particularly for high-performance sensing applications. This study has been conducted by using two PnC designs (periodic and quasi-periodic) to detect the CO₂ pollution in the surrounding air through a wide range of concentrations (0-100%) and temperatures (0-180 °C). The detection process is physically dependent on the displacement of Fano resonance modes. The performance of the sensor is demonstrated for the periodic and Fibonacci quasi-periodic (S₃ and S₄ sequences) structures. In this regard, the numerical findings revealed that the periodic PnC provide
