    Several papers reporting on cognitive function and exposure to cell-phone RF fields have appeared in scientific journals. Human subjects exposed to cell-phone fields showed faster responses in simple reaction time and in choice reaction time. In addition, some investigations have found exposure to cell-phone fields has a facilitating effect on tasks that require attention and manipulation of infor... View full abstract»

  • Revisiting electromagnetic theory

    Publication Year: 2003, Page(s):48 - 51
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (332 KB) | HTML iconHTML

    This paper is addressed primarily to teachers of electromagnetic theory and their graduate students. It poses the question, "If we could start from scratch, are there changes we could make in the development of the theory that would simplify and/or clarify the exposition?" In what follows, a case is made that the answer to this question is "yes." However, the intent is not to urge anyone to change... View full abstract»

    For the last 18 years, our group has been developing a variety of near-field-to-far-field transformations (NFFFTs) for predicting the far-field (FF) RCS of targets from monostatic near-field (NF) measurements. The most practical and mature of these is based on the reflectivity approximation, commonly used in ISAR imaging to model the target scattering. This image-based NFFFT is also the most compu...

    This paper is a short appendix to [C. Garnet, June 2002], where a classical offset Cassegrain of Gregorian dual-reflector antennas were designed from combinations of prescribed geometric parameters. However, in [C. Garnet, June 2002], the model assumed a point-source feed, and did not take into account the physical dimensions of the feed horn needed to illuminate the subreflector. Now, as in [C. G...

    Can invention be taught? The pursuit of open-ended commercially focused projects provides opportunities for students to use design and problem-solving skills, techniques, and tools in a multi-disciplinary team setting. Through this process, students gain the skills, knowledge, confidence, and commitment to test their inventive and entrepreneurial skills in the world. This paper provides an overvie...

    This paper presents a comparison of a new semi-analytical expression with Gaussian-quadrature formulas for the quasi-static double-surface potential integrals arising in the boundary integral (BI) models of micron-size objects, such as RF-MEMS switches. The integrals considered are the quasi-static Green's functions for the scalar and vector potentials, with constant or linear basis functions over... View full abstract»

    New technologies in communications electronics, such as software-defined radio (SDR) and RF switches implemented using micro-electromechanical systems (MEMS), present new challenges and opportunities for antenna design. In sharp contrast to digital technology where Moore's law reigns, a fundamental law of physics constrains the ability to realize electrically small antennas that are both efficient...
