Abstract: A novel three-port Y-shaped circulator based on magneto-photonic crystals is first experimentally investigated. The band gaps of TE mode for the photonic crystals are calculated by plane wave expansion method. The transmission characteristics of the circulator are simulated by finite element method and the experiments are performed in the microwave regime. At the central frequency of 9.83 GHz, the optimal experimental isolation of –61.11 dB is better than the numerical results.

TL;DR: In this paper, a cross-shaped photonic crystal waveguide formed by a square lattice Al2O3 rods array is numerically and experimentally investigated, and the measured reflection and transmission characteristics of the photonic crystals show a large band gap between 8.62 and 11.554 GHz (relative bandwidth is 29.34%).
Abstract: A cross-shaped photonic crystal waveguide formed by a square lattice Al2O3 rods array is numerically and experimentally investigated. The band gap of the TE mode for the photonic crystals and transmission characteristics of waveguides are calculated by the plane wave expansion method and the finite element method. We perform the experiments in the microwave regime to validate the numerical results. The measured reflection and transmission characteristics of the photonic crystals show a large band gap between 8.62 and 11.554 GHz (relative bandwidth is 29.34%). The electromagnetic waves are transmitted stably in the waveguides, and the transmission characteristics maintain a high level in the band gap.

TL;DR: In this paper, the exchange-coupled effect between hard and soft magnetic phases has been investigated in hard/soft (H/S) nanocomposites with establishment of exchange coupled effect between the two phases.
Abstract: Bi-component hard (H) (hexaferrite) and soft (S) (spinel) ferrites nanocomposites are gaining interest scientifically and technically, not only for combining the high magnetization of spinel ferrite nanomaterials and the high coercivity of hexaferrite magnetic nanomaterials but also for the outstanding exchange-coupling behavior among hard and soft magnetic phase. The improved magnetic features lead to produce a new nanocomposite with higher microwave absorption capacity in comparison with ferrites with a single absorption mechanism. Exchange-coupled effect has a potential application based on microwave absorption, recording media, permanent magnets, biomedical and other applications. Intensive studies have been conducted on this topic to produce hard/soft (H/S) ferrite nanocomposites with establishment of exchange coupled effect between the two phases. Preparation methods, microstructure, magnetics features, microwave and dielectric properties, and applications are elaborated. Consequently, a comprehensive effort has been made to contain an original reference investigating in detail the precise outcomes of the published papers.

TL;DR: In this article, a ternary planar photonic crystal (TPPC) consisting of periodic unit cells of dispersive materials is proposed to investigate the propagation of the electromagnetic radiation in the proposed structure.
Abstract: In this work, we propose novel structures of one-dimensional ternary planar photonic crystals (1D-TPPC) consisting of periodic unit cells of dispersive materials. The transfer matrix method (TMM) is utilized to investigate the propagation of the electromagnetic radiation in the proposed structure. The transmittance spectrum and Floquet-Bloch theorem are used to determine the features of the photonic band gap (PBG) for the transverse electric (TE) mode of the incident radiation. In particular, the photonic band gap width (PBGW) is studied as a function of the number of unit cells, thicknesses of layers, angle of the incidence and temperature. Based on the results obtained, the proposed structures are believed to be promising in designing wide angle infrared reflectors.
