Journal ArticleDOI
Numerical Analysis on Transmission Efficiency of Evanescent Resonant Coupling Wireless Power Transfer System
TL;DR: In this paper, a practical wireless power transmission system consisting of a large rectangular wire loop and a small square wire loop with a parasitic square helical coil is proposed for use as an efficient evanescent resonant coupling WPT system in an indoor environment.
Journal ArticleDOI
Novel Broadband Planar Reflectarray With Parasitic Dipoles for Wireless Communication Applications
TL;DR: In this paper, a broadband planar reflectarray with parasitic dipoles is presented for wireless communication applications, which can effectively extend the reflection phase range beyond 360°, which overcomes the problem of an inadequate phase range when using thicker substrates for a wider operational bandwidth.
Journal ArticleDOI
Tunable multi-band terahertz absorber using a single-layer square graphene ring structure with T-shaped graphene strips.
TL;DR: A tunable dual-band terahertz metamaterial absorber with near-unity absorption using single-layer square graphene ring structure with T-shaped graphene strips with polarization-independent and incident-angle-insensitive properties is numerically demonstrated.
Journal ArticleDOI
Frequency Selective Reflectarray Using Crossed-Dipole Elements With Square Loops for Wireless Communication Applications
TL;DR: A new frequency selective reflectarray (FSR) comprising a crossed-dipole array and a frequency selective surface (FSS) of square loops printed on both sides of a dielectric substrate is presented for wireless communication applications.
Journal ArticleDOI
Accurate DOA estimation using array antenna with arbitrary geometry
TL;DR: In this article, a universal steering vector (USV) whose locus is equivalent to the array element pattern is applied to the direction of arrival (DOA) estimation by multiple signal classification (MUSIC) algorithm.
