Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells
Advanced Functional Materials, EarlyView.Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Electronics Letters, 1969 Multiring-antenna arrays are considered, particularly for space telemetry and communication. The configuration with two concentric rings is examined. The distant electric field, the radiation resistance, the directive gain and the mutual-coupling impedances are derived. Numerical results are given for arrays with eight monopoles in each ring.
