Optical & microwave phenomena as a research area investigates the generation, propagation, interaction, and detection of electromagnetic radiation spanning the optical (visible, ultraviolet, infrared) and microwave spectral ranges, with emphasis on their underlying physical mechanisms and cross-regime analogies. It encompasses coherent and incoherent light–matter interactions, waveguiding, scattering, nonlinear effects, resonances, and quantum electrodynamical aspects, as well as microwave cavity dynamics, dispersion, and near-field behavior. The field supports development of advanced spectroscopies, imaging modalities, communication and sensing technologies, and enables engineered materials and structures (e.g., photonic and microwave metamaterials) that tailor electromagnetic response across these frequency bands.
