Characterization of Continuous Electromagnetic Manifolds via Calculus of Variations

Kuranage Roche Rayan Ranasinghe, Miguel Rodrigo Castellanos, Giuseppe Thadeu Freitas de Abreu

We present a novel calculus of variations (CoV)-based framework for the characterizing of, and beamforming over, continuous electromagnetic manifolds of arbitrary multiple-input mu…

Optimality of Bang-Bang Switching for Breaking the Chu Limit via Time-Modulated Matching

Mohamed Akrout, Miguel Rodrigo Castellanos

This paper shows that surpassing the Chu limit on -factors via time-modulated matching requires non-smooth switching strategies. We derive a nonlinear differential condition to…

A Novel Framework for the Characterization of Continuous Electromagnetic Manifolds

Kuranage Roche Rayan Ranasinghe, Miguel Rodrigo Castellanos, Giuseppe Thadeu Freitas de Abreu

A unified framework for the characterization of continuous electromagnetic (EM) manifolds for arbitrary multipleinput multiple-output (MIMO) system geometries is presented. The EM…

The Tri-Hybrid MIMO Architecture

Robert W. Heath, Joseph Carlson, Nitish Vikas Deshpande +3

We present an evolution of multiple-input multiple-output (MIMO) wireless communications known as the tri-hybrid MIMO architecture. In this framework, the traditional operations of…

Towards 6G MIMO: Massive Spatial Multiplexing, Dense Arrays, and Interplay Between Electromagnetics and Processing

Emil Björnson, Chan-Byoung Chae, Robert W. Heath +7

The increasing demand for wireless data transfer has been the driving force behind the widespread adoption of Massive MIMO (multiple-input multiple-output) technology in 5G. The ne…

Electromagnetic manifold characterization of antenna arrays

Miguel R. Castellanos, Robert W. Heath

Antenna behaviors such as mutual coupling, near-field propagation, and polarization cannot be neglected in signal and channel models for wireless communication. We present an elect…
