Optical metasurfaces, as a two-dimensional counterpart of metamaterials, have garnered much attention in the scientific community due to the versatile capabilities to manipulate electromagnetic (EM) waves within an ultrathin surface (Chen et al., 2016; Genevet et al., 2017; Luo, 2019; Monticone...
Realizing signal conversion between optical and microwave frequencies is a crucial step to construct hybrid communication systems that combine both optical and microwave wireless technologies to achieve better features, which are highly desirable in the future wireless communications. However, such a signal...
Recent emergence of metasurfaces has enabled the development of ultra-thin flat optical components through different wavefront shaping techniques at various wavelengths. However, due to the non-adaptive nature of conventional metasurfaces, the focal point of the resulting optics needs to be fixed at ...

Acoustic computing devices, including switches, logic gates, differentiator and integrator, have attracted extensive attentions in both academic research and engineering. However, no scheme of acoustic computing device with more complex functionality has been proposed, such as ordinary differential equation ...
The sensor's versatility is further illustrated through its application in encoding operations, leveraging on the transmittance values to perform logic functions. A polynomial regression model was developed to interpolate absorption values at intermediate frequencies, achieving an R 2 value of 1.0, ...
All-optical logic gatesIn this paper, we propose a novel method for designing all-optical logic gates based on the coherent perfect absorption principle in graphene-based metasurface in terahertz (THz) region. The proposed structure allows us to access AND, OR, and XOR logic operations by ...
Optical logic gates play important roles in all-optical logic circuits,which lie at the heart of the next-generation optical computing technology.However,the intrinsic contradiction between compactness and robustness hinders the development in this field.Here,we propose a simple design principle that ...
The independent control of individual resonances was leveraged to realise NOR and NAND logic gates, demonstrating the capability for selective resonance modulation. This approach enhances the modulation of terahertz resonances and provides a promising framework for developing advanced terahertz modulators....
