In this paper we generalize the adjoint method of inverse design to nonreciprocal media. As a test case, we use three-dimensional topology optimization via the level-set method to optimize one-way energy transfer for pointlike source and observation points. To achieve this we introduce a suite of tools, chiefly what we term the “Faraday-adjoint” method which allows for efficient shape optimization in the presence of magneto-optical media.

Russia and China teamed up on a major military exercise off the coast of Alaska last week, according to a new report. The Wall Street Journal said the 11-ship force “appeared to be the largest such flotilla to approach American shores,” citing experts it did not name. Four U.S. destroyers and P-8 Poseidon aircrafts kept a wary eye on the ships. “It is a historical first.

Superposing multiple plane waves can generate helicity lattices in which the optical helicity varies regularly in space. Here we propose an inverse design method for constructing arbitrary helicity structures based on placing a digital object consisting of dielectric inclusions in three-dimensional space. We apply the method to design structures that reproduce two-dimensional lattices embedded within a three-dimensional region using only a single plane wave as an input.
