Abstract Optically transparent microwave absorbers based on metamaterials demonstrate exceptional absorption performance while maintaining high optical transmittance, showcasing significant potential for applications in modern communication, defense, and architectural fields. Transparency the visible light spectrum is primarily achieved through material selection structural optimization. The artificially designed resistive films can be used to achieve devices with excellent wave characteristics frequency band. In this paper, we systematically review research progress domain of optically metamaterial absorbers. We first introduce implementation principles from perspectives transparency absorption, laying foundation in-depth discussions subsequent sections. Subsequently, focus are classified into three types: passive absorbers, tunable adaptive Passive further discussed their classifications. This paper summarizes current status technical bottlenecks envisioning extensive stealth technology, wireless multifunctional devices. While challenges persist balancing thickness, bandwidth future advancements novel material, innovative designs, manufacturing processes expected enable realization efficient, intelligent,
