Design task of optical coating using an active learning scheme. (a) Solar irradiance (air mass 1.5 global), transmission efficiency (highlighted by a red-dotted line), and the corresponding transmitted irradiance of an ideal TRC structure as a function of wavelength. (b) Schematic of the TRC structure, where the PML structure is encoded into a binary vector for input training data in ML. The schematics are created by Microsoft PowerPoint.
