Non-Abelian phenomena arise when the sequence of operations on physical systems
influences their behaviors. By possessing internal degrees of freedom such as polarization …

Nonreciprocal transmission, resulting from the breaking of Lorentz reciprocity, plays a pivotal
role in nonreciprocal communication systems by enabling asymmetric forward and …

The electromagnetic (EM) beam manipulations such as spatial scanning have always been
the focus in information science and technology. Generally, the transmitting and receiving …

The bidirectional asymmetric transmission (BAT) meta‐devices have attracted widespread
attention as an emerging display, encryption, and information storage platform. Generally …

Transformation optics (TO) or transformation acoustics (TA) theory provides an elegant
framework for designing intricate wave-material interaction devices. Combining TO or TA …

Shear nonreciprocity, implying unequal shear forces in opposite shear directions, can be
achieved by arranging structures asymmetrically. However, the nonreciprocal Poynting …

Artificial media provide a unique playground to test fundamental theories, allowing one to
probe the laws of electromagnetism in the presence of hypothetical axions. While some …

Metasurface, comprising subwavelength unit cells, offers a flexible modulation of the optical
phase. However, traditional metasurfaces are typically engineered to function solely in one …

We report on numerical studies of microwave bianisotropies by magnetochiral (MCh)
metasurfaces consisting of double Z-type gammadions with perpendicularly magnetized …

Jamming enemy detectors' capture of one's own targets has been a long-standing research
topic. Invisibility cloaks have long been revered as a form of camouflage. However, these …
