Carbon Energy, EarlyView.Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Cavity-Backed Wide Slot Antenna
IEE Proceedings H: Microwaves, Antennas and Propagation, 1989We propose a wide slot antenna to expand the frequency bandwidth of a cavity-backed slot antenna. In the antenna the slot width is significant in comparison with the slot length. We present the analysis of the antenna including the feed line. The result obtained is a 35% frequency bandwidth (VSWR < = 2), which is also verified by experiment.

Cavity-backed antenna integrating a self-oscillating mixer
Microwave and Optical Technology Letters, 1999 An active cavity‐backed antenna with self‐mixing capabilities is demonstrated. The FET oscillator operates at the resonance of the cavity in order to reduce the LO signal radiation. Experimental results show good performance in terms of isotropic conversion gain and radiation patterns.

Cylindrical Cavity-Backed Antenna
IEEE Antennas and Wireless Propagation Letters, 2009A cylindrical cavity-backed antenna excited by Hertzian dipoles is investigated. A Green's function approach is used to account for arbitrarily oriented dipoles. Scattered fields are expanded in terms of eigenfunctions, and boundary conditions are enforced to obtain a set of simultaneous equations.

Aircraft Cavity-Backed Nonprotruding Wideband Antenna
IEEE Antennas and Wireless Propagation Letters, 2012A novel circular aperture antenna is presented. The proposed nonprotruding antenna is composed of a cylindrical cavity embedding an inverted hat antenna whose profile is defined by three elliptical segments. This profile can be used to control and shape the return loss response over a wide frequency band (31% at -15 dB). The present design combines the

Wideband cavity-backed bowtie antennas
2009 IEEE International Workshop on Antenna Technology, 2009For wideband antennas with unidirectional patterns, it is a troublesome problem to stabilize the antenna patterns across a very large frequency band. In our work, cavity-backed structures are utilized with bowtie exciters. The patterns of the proposed cavity-backed triangular bowtie antenna (TBA) with rounded corners can be stabilized within a 92 ...
