Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

EPJ Applied Metamaterials, 2019 In this paper, we consider cube-shaped unit cells including high-ε dielectric cubes under magnetic dipole-like resonance placed at the center and metallic mesh wires for negative permittivity to construct three-dimensional quasi-isotropic metamaterials ...

The Euler Number of Bloch States Manifold and the Quantum Phases in Gapped Fermionic Systems
, 2013 We propose a topological Euler number to characterize nontrivial topological phases of gapped fermionic systems, which originates from the Gauss-Bonnet theorem on the Riemannian structure of Bloch states established by the real part of the quantum ...

Advanced Optical Materials, EarlyView.A polymer–perovskite composite obtained by mechanochemical synthesis enables thick, tunable active layers for efficient absorption of highly penetrating ionizing radiation. Vertical‐electrode detectors achieve low X‐ray detection limits and high sensitivity direct 5 MeV proton sensing.

Description of Bloch spaces, weighted Bergman spaces and invariant subspaces, and related questions
Kuwait Journal of Science, 2016 Let D be the unit disc of complex plane C, and H=Hol(D) the class of functions analytic in D. Recall that an f∈Hol(D) is said to belong to the Bloch space B=B(D) if ‖f‖_{B}:=sup_{z∈D}(1-|z|²)|f′(z)|

A problem on spaces of holomorphic maps and the geometry of image domains
Concrete OperatorsWe present an old problem in Geometric Function Theory: characterizing the domains Ω⊂C ${\Omega}\subset \mathbb{C}$ for which every holomorphic map from the unit disk into Ω must belong to a specific function space X.

Projections, the Weighted Bergman Spaces, and the Bloch Space [PDF]
Proceedings of the American Mathematical Society, 1990 The author extends some results of \textit{F. Forelli} and \textit{W. Rudin} [Indiana Univ. Math. J. 24, 593-602 (1974; Zbl 0297.47041)] and \textit{K. Zhu} [J. Funct. Anal. 81, No.2, 260-278 (1988; Zbl 0669.47019)]. Let B be the unit ball in \({\mathbb{C}}^ n\). H(B) denotes the class of holomorphic functions on B.

Terahertz Bloch oscillator with suppressed electric domains: Effect of elastic scattering
, 2005 We theoretically consider the amplification of THz radiation in a superlattice Bloch oscillator. The main dilemma in the realization of THz Bloch oscillator is finding operational conditions which allow simultaneously to achieve gain at THz frequencies ...

Advanced Optical Materials, EarlyView.Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.
