In-situ inverse design of plasma metamaterials

Inverse design methodology have been fruitfully applied to electromagnetically active systems for the last decade where improved computational resources, algorithms, and new manufacturing techniques have enabled the creation of novel performant devices that would otherwise be impossible to produce for exotic applications like optical computing. We explore how tunable plasma elements enable us to conduct the inverse design process entirely in-situ, leading to ~100x improvements in device performance over traditional in-silico inverse design. Moreover, devices with complicated 3D geometry can be created, something that is impossible with in-silico inverse design. We explore how in-situ optimization can be used to improve our low-cost computational models and drive our fundamental understanding of low-temperature plasma forward.
