Wideband QAMC reflector’s antenna for low profile applications

Autor: Stephane Mallegol, A. C. Lepage, Michel Jousset, Xavier Begaud, J. M. LeMener, Michael Grelier

Publikováno v: Applied Physics A. 103:809-813

A wideband reflector’s antenna based on quasi-artificial magnetic conductor is proposed. To validate the design, an Archimedean spiral has been backed to this new reflector. In comparison to classical solution using absorbent material, the prototyp

Publikováno v: Applied Physics A. 103:805-808

AMC and EBG behaviors are respectively characterized by reflection phase method and dispersion diagram. A fast and simple analytical model based on transmission line theory is proposed for each analysis. The validity of these analytical methods is ve

This paper presents a method to improve the circular polarization of an Archimedean spiral antenna placed over a radial Artificial Magnetic Conductor (AMC). Results have been compared with the same radiating element over a more classical AMC reflecto

A methodology is introduced for designing wideband, compact and ultra-thin high impedance surfaces (HIS). A parametric study is carried out to examine the effect of the periodicity on the electromagnetic properties of an HIS. This approach allows des

Synovial Cyst of Sternoclavicular Joint as Mediastinal Mass

Autor: Joe G. Hardin, J. Michael Grelier

Publikováno v: Annals of Internal Medicine. 83:525

Excerpt The sternoclavicular joint is commonly involved in rheumatoid arthritis, but a synovial cyst of this joint has not been recognized as a clinical problem. We report here a patient with such ...
