Abstract Frequency-selective heat infrared (IR) detectors are promising for numerous new apps such as solar cell detection, gas analysis, multi-color imaging, multi-channel detector, recognition of artificial objects in a natural setting, but these features involve extra filters which lead to elevated costs. Plasmonic metamaterial absorbers (PMAs) can impart frequency selectivity to standard heat, IR detectors merely by regulating the absorber surface geometry to generate surface plasmon resonance at the desired frequency. We present a nanoantenna-based mid-infrared absorber for heat infrared detectors. Our structure uses a portion of the noble metal used in standard absorbers and is only one layer thick, which enables incredibly tiny thermal conductivity leading to possibly very low thermal detector noise. Simulation results show that the proposed nanoantennas can achieve a harvesting efficiency of 40% at a frequency of 150 THz where the antenna input impedance is matched to that of fabricated rectifying devices. Achieve maximum bandwidth Absorber from 100 to 200 THz for application purposes energy harvesting sensor. Keywords Nano antenna · Plasmonic metamaterial · Optical absorption · Metal characteristics
1 Introduction Plasmonic perfect absorbers (PPAs) have been received great attention because the waves absorbed and enhanced in the plasmonic nanostructures have been used promisingly in the field of nanophotonics (Luo et al. 2019; Chau et al. 2010; Liu et al. 2016, 2019a, b, c; Rhee et al. 2014; Shinpei and Masafumi 2018; Gao et al. 2019; Li et al. 2019). In metal nanostructures which can be exploited to execute PPAs by suitable design (Hsieh et al. 2016; Liu et al. 2015a, b, 2016, 2017, 2018; Chen et al. 2019; Huang et al. 2017), nature Ohmic * A.

losses are typically unavoidable. Most recent research groups have been focusing on optimizing absorption of PPAs for plasmonic sensing applications (Wu et al. 2016; Yong et al. 2016). The wide range of applications for energy processing, sensing and photocatalysis is a source of researchers ‘great interest in perfect absorption (Wang et al. 2020; Wu et al. 2020; Yi et al. 2019). Surfaces with adjustable optical properties, including applications such as (Adato et al. 2009; Wu et al. 2011; Li et al. 2013; Chen et al. 2015) controlled light absorption (Ogawa et al. 2015) and color printing, have been extensively studied and are of interest for sensing (Tan et al. 2014; James et al. 2016; Miyata et al. 2016).
