The design of all-passive nonreciprocal metastructures is a challenging task as there are trade-offs between the nonreciprocal transmission ratio and insertion loss. Here, Mahmoud et al. propose a concept for all-passive, high-throughput metastructures that exhibit nonreciprocal properties and wave-flow isolation.
