A Frequency-Space Terahertz Transceiver Chip for Multi-Agent Communications and Spatial Awareness
Xiaoyue Xia, Zhicheng Lin, Hao Guo +7
Future indoor embodied-intelligence systems require scalable hardware platforms that support both high-capacity multi-agent connectivity and mutual spatial awareness. The terahertz…
Freeform super-oscillatory optics for CMOS-integrated THz super-resolution imaging
Jin Chen, Liang Gao, Hao Guo +5
The diffraction limit fundamentally constrains the spatial resolution of far-field imaging systems. While near-field techniques can circumvent this limit, their inherently short wo…
An integrated super resolution THz 3D imaging system based on a linear nonlocal achromatic freeform Bessel beam lens and high power oscillator radiator array
Jin Chen, Liang Gao, Hao Guo +5
High performance terahertz (THz) 3D imaging is critical for non-destructive evaluation. However, conventional architectures are fundamentally limited by severe chromatic aberration…
Inverse design of 3D-printable metalenses with complementary dispersion for terahertz imaging
Mo Chen, Ka Fai Chan, Alec M. Hammond +2
This study formulates a volumetric inverse-design methodology to generate a pair of complementary focusing metalenses for terahertz imaging: the two lenses exhibit equal and opposi…
