Microwave Metamaterial Antennas and Other Applications. Tie Jun Cui and Hui Feng Ma.7. B. Zhou, H. Li, X. Y. Zou, and T. J. Cui, "Broadband and high-gain planar Vivaldi antennas based on inhomogeneous anisotropic zero-index metamaterials," Progress in Electromagnetic Research, vol... Loughborough Antennas & Propagation Conference, 2012, UK 3) Graphene ‘patch’ antennas at microwave Though antennas with good efficiency cannot be realized at micro mm-wave using graphene, they might still be interesting for integration andBy proper adjustment of the dimensions, a tunable polarizer was designed, whose performance is shown in Fig. Design and performance investigation of tunable UWB thz … In this paper a tunable antenna using graphene - based fractal shape artificial magnetic conductor (AMC) is propose d for ultra - wideband (UWB) terahertz (THz) application. The resonance frequency of the proposed antenna can be tuned by varying the applied DC voltage which leads to variation in... Detection of electromagnetic waves All devices based on graphene are ambipolar, i.e. they can work based on either electrons or holes.The detection of electromagnetic waves in the microwave spectrum implies a nonlinear device able to demodulate a microwave fieldA graphene. slot-patch antenna is displayed in Fig.
Graphene offers multiple functions of signal transmission, emission, modulation, and detection in a broad band, high speed, compact size, and low loss. Here, we have a brief view of graphene based functional devices at microwave, terahertz, and optical frequencies. Their fundamental physics and computational models were discussed as well.

The design of a wideband single-layer dual-band ... A design for a broadband single-layer dual-band reflectarray antenna is presented. A genetic algorithm is employed to design and optimize the element of the antenna. The basic idea to improve the bandwidth of the proposed antenna is based on increasing the range of the linear region of the phase response of the microstrip element. Graphene based functional devices: A short review

dielectric resonator antenna: Topics by WorldWideScience.org On top of the slot there is an air cavity and on top, a small portion of a hemispherical lens. The fractional bandwidth of such antennas is around 10 percent, which is good enough for heterodyne imaging applications.The new geometry makes … Best Paper Finalists — Eucap 2016 Lars Foged; Francesco Saccardi (Microwave Vision Italy); Andrea Giacomini (Microwave Vision Italy (MVI)); IMS2019 Technical Sessions | IMS2019 A novel method using dual-mode cavities to create transmission zeros, a folded ridge waveguide dual-band tunable bandstop filter, and a filter using a resonant inverter structure will also be presented.
