Full-Wave Harmonic Balance Framework for Dispersive Time-Varying Photonic Structures
Mohammad R. Tavakol, Wenshan Cai
Time-varying photonic structures redistribute electromagnetic energy among Floquet harmonics, enabling frequency conversion, nonreciprocity, parametric gain, and dynamic wavefront…
MxDiffusion: A Physics-Aware Maxwells Law-Guided Diffusion Model Strategy for Inverse Photonic Metasurface Design
Sujoy Mondal, Taehyuk Park, Sudipta Biswas +2
We introduce MxDiffusion, a hybrid physics- and data-driven diffusion-based framework that enables efficient and highly accurate generation of photonic structures from target optic…
Nonreciprocal Negative Refraction Enabled by Photonic Time Crystals
Mohammad R. Tavakol, Wenshan Cai
We propose and theoretically demonstrate nonreciprocal negative refraction enabled by time-varying photonic structures. By engineering temporal modulations at the interfaces of hyp…
Ion-Assisted Nanoscale Material Engineering in Atomic Layers
Hossein Taghinejad, Mohammad Taghinejad, Sajjad Abdollahramezani +11
Achieving deterministic control over the properties of low-dimensional materials with nanoscale precision is a long-sought goal. Mastering this capability has a transformative impa…
