News Comment EM modeling: Finding ground in an EM simulator … and learning how to use it The concept of ground, simple though it may seem, can confound novices and veterans alike when applied to highfrequency design tools, which is not surprising since circuit simulators require a global ground and EM simulators do not consider ground at all. So it’s our job to ensure that EM results (S-parameters) are properly interpreted by the circuit simulator. RF/microwave materials: Polymer advances RFID security — Nanotube switching effect discovered — 90 GHz graphene transistor research gains another adherent X-Parameters: The new paradigm for measurement, modeling, and design of nonlinear RF and microwave components X-parameters are the supersets of S-parameters, load-pull, and waveform measurements. They unify high-frequency characterization, modeling, and design of nonlinear microwave and RF components and systems. We can measure and extract X-parameters with the Agilent NVNA, model the component in Agilent ADS with X-parameters encapsulated by the PHD component, and design nonlinear circuits and systems with X-parameters in ADS. Advanced processor allows system designers to overcome challenges in next-generation enterprise-class wireless access points Meeting the price, performance, power and security challenges of 802.11n using 32-bit RISC communication processors. 14 16 ADVERTISING PRODUCTION LYDIA GIJSEGOM Tel +32 (0) 2 740 00 50 email: lydia.gijsegom@eetimes.be CIRCULATION & FINANCE LUC DESIMPEL Tel +32 (0) 2 740 0055 email: luc.desimpel@eetimes.be ART MANAGER JEAN-PAUL SPELIERS Tel +32 (0)2 740 0052 email: jean-paul.speliers@eetimes.be ACCOUNTING RICARDO PINTO FERREIRA Tel +32 (0)2 740 0051 email: financial@eetimes.be SALES DIRECTOR GEERT DE VUYST Tel +32 2 740 0050 email: sales@eetimes.be PUBLISHER ANDRE ROUSSELOT Tel +32 (0)2 740 0053 email: andre.rousselot@cmp.com EUROPEAN BUSINESS PRESS A CMP COMPANY 144 Avenue Eugène Plasky 1030 Brussels - Belgium Tel: +32 (0)2 740 00 50 Fax: +32 (0)2 740 00 59 www.mwee.com VAT Registration: BE 461.357.437 RPM: Brussels Company Number: 0461357437 © 2008 E.B.P.
