 Morphology-dependent resonance

Morphology-dependent resonance (MDR) is a phenomenon in optics and electromagnetics that occurs in microscale and nanoscale particles, particularly in resonant structures such as micro-spheres, nano-spheres, and other shapes. It refers to the way that the shape, size, and material properties of a particle influence its interaction with light, specifically how light can be resonantly enhanced at certain wavelengths based on the particle’s morphology.
