Modulated phononic crystals: Non-reciprocal wave propagation and Willis materials (2017, methodology): “The transformation method introduced by Greenleaf et al. (20 03a , 20 03b) , and later by Leonhardt (2006) and Pendry et al. (2006) , provided an efficient route to cloaking devices for phenomena governed by equations that are form-invariant by coordinate transformations such as the conductivity equ”
Topological acoustics (2022, background): “The second example is an acoustic analog of the Zeeman effect in a ring cavity with circulating airflow [22].”
Topological photonics (2018, background): “One can also switch the role of phonon and photons and study nonreciprocal transport of phonons (Habraken et al., 2012; Stannigel et al., 2012; Fleury et al., 2014; Kim et al., 2017).”
Artificial gauge fields in materials and engineered systems (2017, neutral): “However, if such terms were to be realized, for instance, with acoustic structures that contain a circulating fluid [212,213], unidirectional topological edge states would be expected to exist [214].”

Experimental realization of optomechanically induced non-reciprocity (2016, background): “[9] reported the sound analogue of isolation due to a circulating fluid medium.”
Tunable topological phononic crystals (2015, background): “According to the superposition principle, the acoustic wave circulates inside the ring at different velocities, cþ v and c − v, which leads to the splitting of the resonance frequencies as follows: ω 1⁄4 ðc vÞ=Rav, where Rav 1⁄4 ðr0 þ r1Þ=2 is the average of the inner and outer radii, and ω0 1⁄4 c=R”
Magnetless Microwave Circulators Based on Spatiotemporally Modulated Rings of Coupled Resonators (2016, background): “This concept was experimentally proven in acoustics by circulating air in a ring resonator, thereby demonstrating the first-ever acoustic circulator [36].”
