Locating Transient Directional Sources in Free Space Based on the Electromagnetic Time Reversal Technique

Marcos Rubinstein, Farhad Rachidi-Haeri, Qi Li

Traditional location methods such as time of arrival and direction of arrival have been widely used to locate transient radiation sources. However, these approaches neglect the directional radiation pattern of the sources. Locating directional sources is a ...

Patch Antenna System for CubeSats in L band

Anja Skrivervik, Miroslav Veljovic

An L-band patch-antenna system for CubeSat applications is presented in this paper. The high-permittivity dielectric loading reduces the size of individual antennas to make them suitable for a CubeSat platform. Two circularly polarized patch antennas were ...

Broadbeam microstrip patch antenna using higher order modes

Anja Skrivervik, Ismael Vico Triviño

The aim of this contribution is to assess the potential of using various microstrip radiating elements excited with different modes to achieve wide pattern beamwidths. The proposed antenna is made in classic microstrip technology and consists of a circular ...

Gain enhancement of circular waveguide antennas using near-zero index metamaterials

Kosmas Tsakmakidis, Ershad Mohammadi, Foziyeh Sohrabi

In this article, a rigorous analytical methodology is introduced for designing near-zero refractive index metamaterials (NZIMs). Our proposed NZIM media is realized by three stacked layers of perforated metallic surfaces, each layer composed of a fishnet-l ...

Silicon Photonic MEMS Phase-Shifter

Niels Quack, Hamed Sattari, Teodoro Graziosi

We present a design for an analog phase shifter based on Silicon Photonic MEMS technology. The operation principle is based on a two-step parallel plate electrostatic actuation mechanism to bring a vertically movable suspended tapered waveguide in a first ...

Optically isolated millimeter-wave detector for the Toroidal Plasma Experiment

Timothy Goodman, Stefano Alberti, Anja Skrivervik, Ivo Furno, Marcelo Baquero Ruiz, Gennady Plyushchev, Oulfa Chellaï, Fabian Manke

We have designed and built an optically isolated millimeter-wave detection system to prevent interference from a nearby, powerful, 2.45 GHz microwave source in millimeter-wave propagation experiments in the TORoroidal Plasma EXperiment (TORPEX). A series o ...

Wideband H-plane dielectric horn antenna

Juan Ramon Mosig, Lei Wang, Maria Garcia Vigueras, Marcos Alvarez Folgueiras

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...
