High-NA Achromatic Metalenses by Inverse Design
Haejun Chung, Owen D. Miller
We use inverse design to discover metalens structures that exhibit broadband, achromatic focusing across low, moderate, and high numerical apertures. We show that standard unit-cel…

Maximal Free-Space Concentration of Electromagnetic Waves
Hyungki Shim, Haejun Chung, Owen D. Miller
We derive upper bounds to free-space concentration of electromagnetic waves, mapping out the limits to maximum intensity for any spot size and optical beam-shaping device. For sub-…
