Abstract: To address the urgent demand for multifunctional stealth materials in modern military equipment, this paper proposes an optically transparent metamaterial with radar/infrared compatible stealth capabilities. The structure is composed of an infrared shielding layer (IR-SL), a polymethyl methacrylate (PMMA) matching layer, and a radar absorbing screen (RAS). The IR-SL consists of an array of indium tin oxide (ITO) square patches, which effectively reduces infrared emissivity while allowing radar waves to transmit sufficiently to the underlying layer. The RAS incorporates a lossy layer and a reflective layer constructed from micron-scale metal grid structures. The lossy layer employs a composite grid design with differentiated line widths, which enhances the design flexibility of the absorptive structure while maintaining high optical transmittance. By integrating optically transparent functional layers, the proposed design achieves synergistic optimization of high-efficiency absorption (absorptivity > 90%) under normal incidence within the 6.11 - 16.24 GHz frequency band and low infrared emissivity (ε = 0.31). Experimental validation based on fabricated prototypes confirms its characteristics of optical transparency, broadband radar absorption, and low infrared emissivity, offering a novel solution for special functional components such as aircraft canopies and optoelectronic sensor windows.
