Simulation and Detection of Photonic Chern Insulators in One-Dimensional Circuit Quantum Electrodynamics Lattice

, 2015
We introduce a simple method to realize and detect photonic topological Chern insulators with one-dimensional circiut quantum electrodynamics arrays. By periodically modulating the couplings of the array, we show that this one-dimensional model can be ...

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Decoupling Method Based on Complementary Split Ring Resonator (CSRR) for Two Cone Shipborne Antennas

IEEE Access, 2021
Shipborne antenna is the important part in the communication system of modern ships. However, the coupling between shipborne antennas greatly influences their communication performance so an effective decoupling method is needed to address the coupling ...

Phononic band structure engineering for high-Q gigahertz surface acoustic wave resonators on lithium niobate

, 2019
Phonons at gigahertz frequencies interact with electrons, photons, and atomic systems in solids, and therefore have extensive applications in signal processing, sensing, and quantum technologies.

Quasi-Elliptic Higher-Order Tunable Bandpass Filter With Constant Absolute Bandwidth Using Synchronously Tuned Dual-Mode Resonators

IEEE Access, 2023
Designing a higher-order tunable bandpass filter (BPF) with constant absolute bandwidth (ABW) and identical passband response at every passband frequency tuning state is considered a challenge.

Calculation of coupling coefficients for diamond micro-ring resonators

Journal of Applied Physics
We deduce equations to calculate coupling coefficients of diamond micro-ring resonators. The equations can be used universally at any wavelength but not limited to the transmission peaks/valleys, and can be adapted with triangular cross-sections and tapered waveguides.

Mutual Coupling Coefficients of Rotated Rectangular Dielectric Resonators in Open Space

Visnyk NTUU KPI Seriia - Radiotekhnika Radioaparatobuduvannia, 2022
The coefficients of mutual coupling of rectangular dielectric resonators in open space are calculated under the condition of their rotation relative to one of the axes of a given rectangular coordinate system. Analytical formulas for complex coupling coefficients are obtained.
