This manuscript introduces the formation of a microscale array of three fly Ormia ochracea's ears-inspired directional microphones that can realize the directional sensing in three dimensions. The ...

In this paper, we first propose a new design strategy of 2D Z-complementary array quads (2D-ZCAQs) with feasible array sizes. A 2D-ZCAQ consists of four distinct unimodular arrays satisfying zero 2D ...
