Spin and Orbital Angular Momenta of Electromagnetic Waves: From Classical to Quantum Forms
Wei E. I. Sha, Zhihao Lan, Menglin L. N. Chen +2
Angular momenta of electromagnetic waves are important both in concepts and applications. In this work, we systematically discuss two types of angular momenta, i.e., spin angular m…
Non-iterative Methods in Inhomogeneous Background Inverse Scattering Imaging Problem Assisted by Swin Transformer Network
Naike Du, Tiantian Yin, Jing Wang +5
A deep learning-assisted inversion method is proposed to solve the inhomogeneous background imaging problem. Three non-iterative methods, namely the distorted-Born (DB) major curre…
Breaking the Degrees-of-Freedom Limit of Holographic MIMO Communications: A 3-D Antenna Array Topology
Shuai S. A. Yuan, Jie Wu, Hongjing Xu +9
The performance of holographic multiple-input multiple-output (MIMO) communications, employing two-dimensional (2-D) planar antenna arrays, is typically compromised by finite degre…
Electromagnetic Effective-Degree-of-Freedom Limit of a MIMO System in 2-D Inhomogeneous Environment
Shuai S. A. Yuan, Zi He, Sheng Sun +3
Compared with a single-input-single-output (SISO) wireless communication system, the benefit of multiple-input-multiple-output (MIMO) technology originates from its extra degree of…
Approaching the Fundamental Limit of Orbital Angular Momentum Multiplexing Through a Hologram Metasurface
Shuai S. A. Yuan, Jie Wu, Menglin L. N. Chen +9
Establishing and approaching the fundamental limit of orbital angular momentum (OAM) multiplexing are necessary and increasingly urgent for current multiple-input multiple-output r…
