When the feature size of photonic structures becomes comparable or even smaller than the wavelength of light, the fabrication imperfections inevitably introduce disorder that may eliminate many functionalities of subwavelength photonic devices. Here we suggest a novel concept to achieve a robust band gap which can endure disorder beyond 30% as a result of the transition from photonic crystals to Mie-resonant metamaterials. By utilizing Mie-resonant metamaterials with high refractive index, we demonstrate photonic waveguides and cavities with strong robustness to position disorder, thus providing a novel approach to the band-gap-based nanophotonic devices with new properties and functionalities.

A technique of measuring the dielectric properties of materials, which vary over a range of frequencies depending on the physical properties of the material. The technique involves measuring, over a range of frequencies, ELECTRICAL IMPEDANCE and phase shift of an electric field as it passes through the material.
Process of classifying cells of the immune system based on structural and functional differences. The process is commonly used to analyze and sort T-lymphocytes into subsets based on CD antigens by the technique of flow cytometry.
The treatment of immune system diseases by deliberate infestation with helminths. This therapy is partly based on the HYGIENE HYPOTHESIS which states that the absence of parasites increases immune dysregulation because of the lack of stimulation of REGULATORY T-CELLS.
The co-existence of a substance abuse disorder with a psychiatric disorder. The diagnostic principle is based on the fact that it has been found often that chemically dependent patients also have psychiatric problems of various degrees of severity.
Regeneration of normal immune function after immune depleting procedures or infections (e.g., HEMATOPOIETIC STEM CELL TRANSPLANTATION). Delayed and incomplete reconstitution of the ADAPTIVE IMMUNE system in particular involving T-CELLS is associated with increase or relapse of infection.
