Acoustic metamaterial properties of a 2D closed cellular solid with entrained fluid

Metamaterials are often defined as artificial compositions designed to exhibit desired physical properties. These materials attract a lot of research attention due to unusual behavior that may not yet have been seen in nature. Although there is no commonly ...

Modeling of Long-Term Multipactor Evolution in Microwave Components Including Dielectric Layers

Apostolos Sounas

Multipactor is a resonant vacuum discharge occurring in microwave components of satellite systems as well as in particle accelerators. Due to its undesirable effects, multipactor analysis constitutes a mandatory step in the design of modern satellite compo ...

Acoustic Leaky-Wave Antenna

Hervé Lissek, Seyyed Hussein Seyyed Esfahlani, Sami Driss Karkar

In the last years, the number of studies carried out in the field of acoustic metamaterials has significantly increased. In year 2009, our group proposed a concept of acoustic composite right/left hand transmission line (CRLH-TL) metamaterial, consisting o ...

Tunable millimeter-wave phase shifter based on dielectric elastomer actuation

Julien Perruisseau-Carrier, Samuel Rosset, Herbert Shea, Pietro Romano, Oluwaseun Adelowo Araromi

A very low-loss tunable millimeter-wave phase shifter driven by dielectric elastomer actuators (DEAs) is presented. The device consists of a fixed coplanar waveguide (CPW) and two metallic loading strips suspended on an elastomer membrane. The horizontal o ...

Electromagnetic Simulation of CERN Accelerator Components and Experimental Applications

Carlo Zannini

Wakes and impedances of single accelerator elements can be obtained by means of theoretical calculation, electromagnetic (EM) simulations or bench measurements. Since theoretical calculations apply only to simple structures and bench measurements have some ...

Practical issues related to the design of UWB directional couplers in strip line technology

Juan Ramon Mosig, Baptiste Fernand Hornecker

Recently, the study of slot-coupled directional couplers has led to compact and elegant topologies for UWB applications. The most common design consists in two elliptically shaped lines coupled through an elliptically shaped slot in a common ground plane. ...

Resonant RF network antennas for large-area and large-volume inductively coupled plasma sources

Philippe Frédérique Bruno Guittienne, Christoph Hollenstein, Alan Howling

Large-area and large-volume radio frequency (RF) plasmas are produced by different arrangements of an elementary electrical mesh consisting of two conductors interconnected by a capacitor at each end. The obtained cylindrical and planar RF networks are res ...

Time-Domain Generalized Telegrapher's Equations for the Electromagnetic Field Coupling to Finite Length Wires Above a Lossy Ground

Farhad Rachidi-Haeri, Abdolhamid Shoory

In this paper, a time-domain variant of the generalized telegrapher's equations for transient electromagnetic field coupling to a finite-length wire above a lossy half-space is derived. The approach is fully based on the thin-wire antenna theory. The lossy ...
