“…They are circulators (isocirculators) based on different physical effects, filters, switches, commutators, control power dividers, mode convertors and so on [9][10][11][12][13][14][15][16][17][18][19][20].…”

A Systematic Study of Symmetrical Electromagnetic Three-Ports With Isotropic and Gyrotropic Media - Abstract

“…Three-ports with gyrotropic media fulfill nonreciprocal and control functions at microwaves and in optics. They are circulators (isocirculators) based on different physical effects, filters, switches, commutators, control power dividers, mode convertors and so on [9][10][11][12][13][14][15][16][17][18][19][20].…”
