Toward Metantennas: Metamaterial-Based Antennas for Wireless Communications
Antennas have historically been the most common electromagnetic (EM) technology for wireless communication systems. Antenna as hardware is entirely dependent on the EM properties of the materials used, mostly related to the permittivity and permeability. I ...
Piscataway2023A Compressive Sensing Framework for EMI Source Localization Using a Metalens Structure: Localization Beyond the Diffraction Limit
Marcos Rubinstein, Mohammad Azadifar, Hamidreza Karami
In this article, we propose a novel approach for the localization of electromagnetic interference (EMI) sources based on the concept of compressive sensing and metalenses. We show that using the spatial and frequency dispersion offered by the metalens, we ...
2022Localization of Electromagnetic Interference Sources Using a Time-Reversal Cavity
Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Hamidreza Karami
In this article, we propose and implement a novel technique to locate electromagnetic interference (EMI) sources using the concept of time-reversal (TR) cavity. We show in an intuitive manner that reflections from the surfaces of a cavity can emulate an in ...
2021Time-Varying Components for Enhancing Wireless Transfer of Power and Information
Romain Christophe Rémy Fleury, Mohammad Sajjad Mirmoosa, Xuchen Wang
Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time and frequency domains. For engineering time-modulated systems, one needs to th ...
2021Electromagnetic waves under nonstationary conditions, the connection with parity-time symmetry and studies on resonant systems
In this thesis, the electromagnetic wave propagation is studied in nonstationary-medium scenarios. The electromagnetic fields under material time-modulation are shown to conserve their momentum but not their energy. The mathematical foundations and analysi ...
EPFL2021Zero Index Metamaterial for High Gain Array
Many metamaterials, including metal wire grid, was invented to enhance the performance of the antenna in the last decade. A novel zero index metamaterial (ZIM), consisting of double metal layers with periodic circular perforation cells, was proposed and st ...
IEEE2020Antennas for CubeSat Communication
CubeSats are a type of small satellites (< 500 kg) that weigh several kilograms and consist of multiple Units (U) measuring 100 × 100 × 113.5 mm3. CubeSats emerged as a low-cost alternative to conventional large satellites, and have since demonstrated capa ...
EPFL2020Antenna for a Cranial Implant: Simulation Issues and Design Strategies
Anja Skrivervik, Zvonimir Sipus, Miroslav Veljovic
The design of a specific antenna for a cranial implant is used to illustrate design and simulation issues linked to implantable antennas. After a brief introduction, we will review the requirements for the antenna, and go through the design process, discus ...
IEEE2020Locating 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 ...
2020Localization of Electromagnetic Interference Source Using a Time Reversal Cavity: Application of the Maximum Power Criterion
Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Hamidreza Karami
The localization of Electromagnetic Interference (EMI) sources is very important in Electromagnetic Compatibility applications. Recently, a novel localization technique based on the Time Reversal Cavity (TRC) concept was proposed using only one sensor. In ...
