Optics is fundamental part of the physics toolkit. I will discuss a range of concepts and methods, covering causality, propagation, as well as the transformation methods that have given us the spatial cloak and spacetime “event” cloak. In particular I will present a new temporally propagated factorization scheme that replicates the success of spatially propagated directional methods, and adds a new tool to the armoury of nonlinear optics modelling. Part of the motivation is that whilst spatially propagated methods are popular in nonlinear optics, not least because of their efficient handling of material (temporal) dispersion, they necessarily violate physical causality. Following that, I will discuss the role of other waves—not just electromagnetic waves—in the context of transformation methods, and how we might unify the process and mechanisms of design for transformation devices.
