Non-Reciprocal Willis Coupling in Zero-Index Moving Media
Li Quan, Dimitrios L. Sounas, Andrea Alu
Mechanical motion can break the symmetry in which sound travels in a medium, but significant non-reciprocity is typically achieved only for very large motion speeds. Here we combin…
What is Nonreciprocity?
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper aims at providing a global perspective on electromagnetic nonreciprocity and clarifying confusions that arose in the recent developments of the field. It provides a gene…
Broadband Cyclic-Symmetric Magnet-less Circulators and Theoretical Bounds on their Bandwidth
Ahmed Kord, Dimitrios L. Sounas, Zhicheng Xiao +1
In this paper, we explore theoretically and experimentally broadband spatiotemporally modulated (STM) magnet-less circulators realized by combining three-port non-reciprocal juncti…
Nonreciprocal Cavities and the Time-Bandwidth Limit
Sander A. Mann, Dimitrios L. Sounas, Andrea Alù
The time-bandwidth limit inherently relates the lifetime of a resonance and its spectral bandwidth, with direct implications on the maximum storage time of a pulse versus its frequ…
What is Nonreciprocity? Part II
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper is the second part of a two-part paper on \emph{Electromagnetic (EM) Nonreciprocity (NR)}. Part~I has defined NR, pointed out that linear NR is a stronger form of NR tha…
Non-reciprocal Components Based on Switched Transmission Lines
Aravind Nagulu, Tolga Dinc, Zhicheng Xiao +4
Non-reciprocal components, such as isolators and circulators, are critical to wireless communication and radar applications. Traditionally, non-reciprocal components have been impl…
