Multiobjective Optimization of Medium-Frequency Transformers for Isolated Soft-Switching Converters Using a Genetic Algorithm

Alfred Rufer, Asier Garcia Bediaga, Irma Villar, Alejandro Rujas

The main challenge of medium-frequency transformers is the number of design parameters, constraints and objectives, and the difficulty of handling them on a particular design. This paper presents a novel computer-aided optimal design for MF transformers us ...

A Switched Oscillator Geometry Inspired by a Curvilinear Space-Part II: Electrodynamic Considerations

This is the second part of a two-part paper in which we present a new technique for the design of coaxial switched oscillators (SWOs). In this part, we present a model for the analysis of the signal radiated by the SWO, in both frequency and time domains. ...

A Methodology to Reduce the Computational Effort in the Evaluation of the Lightning Performance of Distribution Networks

The estimation of the lightning performance of a power distribution network is of great importance to design its protection system against lightning. An accurate evaluation of the number of lightning events that can create dangerous overvoltages requires a ...

Exploiting the leaky-wave properties of transmission-line metamaterials for single-microphone direction finding

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

A transmission-line acoustic metamaterial is an engineered, periodic arrangement of relatively small unit-cells, the acoustic properties of which can be manipulated to achieve anomalous physical behaviours. These exotic properties open the door to practica ...

Diminishing SAR for Wearable UHF Antennas

Anja Skrivervik, Jovanche Trajkovikj

This letter presents a study on the specific absorption rate (SAR) evaluation of UHF wearable antennas. A planar inverted-F antenna (PIFA) intended to operate in wireless body area networks (WBANs) is taken as an example for the investigation. The presence ...

Feeding structure influence on performance of two UWB antennas near a human arm

Anja Skrivervik, Mohsen Koohestani

This paper reports a study of the feeding structure influence on impedance matching and system fidelity factor of two loaded UWB antennas when placed near a human arm. To this aim, two identical dielectric loaded versions of the same UWB antenna designs wi ...

On the selection of radiating elements for compact indoor massive-MIMO base stations

Julien Perruisseau-Carrier

Massive-multiple input multiple output (MIMO) was recently proposed as a key solution for improving the performance of multi-user MIMO in future cellular generations. The main paradigm in this novel MIMO technique is to use a very large number of antenna e ...

Small antennas as wireless system components

Nuno Miguel Faria Pires

Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...
