چکیده
• Lightweight and thin MXene/doped-hexaferrite composite that can suppress electromagnetic interference is reported. This suppresses waves dominantly via absorption over the frequency range from 30 to 50 GHz. The 1.5 mm thick MXene/45 wt% doped-hexaferrite shows a broad effective bandwidth of 7 developed MXene/BaCo0.3Ti0.3Fe11.4O19 hexaferrite be promising EM wave absorber material for millimeterwave applications. (EMI) shielding materials with high effectiveness (SE) have been investigated last decade address unreliability issue in all electronic technologies caused by EMI. Herein, we report SE novel Ti 3 C 2 T x (hexagonal ferrite: BaCo 0.3 Fe 11.4 O 19 ) composite. (EM) GHz millimeter-wave (mmWave) Two-dimensional inorganic compound MXene was synthesized using LiF-HCl etching process, particles were prepared conventional solid-state reaction. Then, fabricated mixing MXene/polyvinyl-pyrrolidone (PVP) containing solution particles. composites characterized vibrating sample magnetometer static magnetic properties vector network analyzer dynamic dielectric microwave absorbing performance. A magnetocrystalline anisotropy shifted peak mmWave bands such as K - V-bands, unlike spinel ferrite.

This article compares two popular channel models for 5G wireless communications, the 3GPP TR 38.900 Release 14 and the NYUSIM channel models. Simulation results indicate that the 3GPP channel model yields unrealistic eigenvalues and higher spectral efficiency than NYUSIM, revealing the problematic choice of some channel parameters in the 3GPP model for frequencies above 6 GHz.
متن کاملListen Before Receive for Coexistence in Unlicensed mmWave Bands
Listen-Before-Talk (LBT) has been adopted as the spectrum sharing technique that guarantees a fair LTE/Wi-Fi coexistence in the unlicensed spectrum at the 5 GHz band. Differently, at mmWave bands, where beamforming is a must to overcome propagation limits, LBT scope becomes limited because the interference layout changes due to the directionality of transmissions. In this regard, this paper pro...
