In the Mesoscale Materials Lab we explore how symmetry-breaking in ferroic meta-materials drives the interaction of light and other waves with excitations solids. Welcome to our site.
It is well known how the properties of a solid arise from its symmetry, whether this is defined within the bulk interior, or by the presence of a surface or interface. We study how symmetry-breaking at different length scales alters how light and other electromagnetic radiation interacts and propagates in ferroelectric and related materials.
The domain-wall structure and dynamics are found to enhance, rather than inhibit, the high-frequency performance of an intrinsically tunable material, obtaining ultra-low loss and exceptional frequency selectivity. Illustration credit: Felice Macera. Relevant publication
