Topological Metamaterial for Magnetic Resonance Imaging
Siyong Zheng, Maopeng Wu, Zhonghai Chi +14
Magnetic Resonance Imaging (MRI) is crucial in global healthcare, but the traditional receive coils, as a core component of MRI, SNR enhancement is limited due to the optimization…

Non-Hermitian Complex Coupling for Magnetic Resonance Imaging
Zheng Siyong, Wu Maopeng, Chi Zhonghai +4
Strong coupling in wave-based systems often causes level repulsion, leading to mode splitting and reduced response at the target frequency. This problem is pronounced in magnetic r…

Gain/Loss-free Non-Hermitian Metamaterials
Wu Maopeng, Weng Mingze, Chi Zhonghai +6
The ease of using optical gain/loss provides a fertile ground for experimental explorations of non-Hermitian (NH) physics. Without gain/loss, can we realize the NH effect in a Herm…
