Array Designs for Long-Distance Wireless Power Transmission: State
INVITED PAPER Array Designs for Long-Distance Wireless Power Transmission: State-of-the-Art and Innovative Solutions A review of long-range WPT array techniques is provided with recent advances and future trends. Design techniques for transmitting antennas are developed for optimized array architectures, and synthesis issues of rectenna arrays are detailed with examples and discussions. By Andrea Massa, Member IEEE, Giacomo Oliveri, Member IEEE, Federico Viani, Member IEEE,andPaoloRocca,Member IEEE ABSTRACT | The concept of long-range wireless power trans- the state of the art for long-range wireless power transmis- mission (WPT) has been formulated shortly after the invention sion, highlighting the latest advances and innovative solutions of high power microwave amplifiers.

High Frequency Communications – an Introductory Overview
High Frequency Communications – An Introductory Overview - Who, What, and Why? 13 August, 2012 Abstract: Over the past 60+ years the use and interest in the High Frequency (HF -> covers 1.8 – 30 MHz) band as a means to provide reliable global communications has come and gone based on the wide availability of the Internet, SATCOM communications, as well as various physical factors that impact HF propagation. As such, many people have forgotten that the HF band can be used to support point to point or even networked connectivity over 10’s to 1000’s of miles using a minimal set of infrastructure. This presentation provides a brief overview of HF, HF Communications, introduces its primary capabilities and potential applications, discusses tools which can be used to predict HF system performance, discusses key challenges when implementing HF systems, introduces Automatic Link Establishment (ALE) as a means of automating many HF systems, and lastly, where HF standards and capabilities are headed. Course Level: Entry Level with some medium complexity topics Agenda • HF Communications – Quick Summary • How does HF Propagation work? • HF - Who uses it? • HF Comms Standards – ALE and Others • HF Equipment - Who Makes it? • HF Comms System Design Considerations – General HF Radio System Block Diagram – HF Noise and Link Budgets – HF Propagation Prediction Tools – HF Antennas • Communications and Other Problems with HF Solutions • Summary and Conclusion • I‟d like to learn more = “Critical Point” 15-Aug-12 I Love HF, just about On the other hand… anybody can operate it! ? ? ? ? 15-Aug-12 HF Communications – Quick pretest • How does HF Communications work? a. -

ADVENTISTS AFFIRM : Famine or Feast? http://www.adventistsaffirm.org/article/203/previous-issues/volume-21-... Home > Previous Issues > Volume 21, Number 2 > EDITOR'S CORNER JERRY A. STEVENS Retired General Conference Worker/ Ponderer of Our Changing Times As promised in our last issue, we offer herewith its companion volume devoted to the pulpit ministry. The immediate emphasis falls within the time span extending from the second half of the 20th century up to the present time—in other words, the era of “modern” preaching. But we include, as is our usual practice, timeless counsel from the pen of inspiration. We daresay that if we polled our readers to suggest the single best sermon they ever heard, we would receive a dizzying variety of answers. Be assured, then, that your very favorite sermon is very likely not reprinted here. This is not to say—no, not at all—that we have thrown together a strictly arbitrary anthology of mediocre sermons or “filler” material in the present volume. On the contrary, each sermon has been carefully selected and endorsed by our editorial board. Considered individually, each addresses provocative, sometimes even sensitive, topics. Taken as a whole, they represent a wide spectrum of current trends and concerns—some highly alarming—among us as a people. The names of the speakers, for the most part, may be familiar to most of our readers. We would like to suggest, however, that each reader make a concerted effort to “listen” very attentively to the “spoken” word. See whether the Holy Spirit just now may be spreading a banquet table in the wilderness—a veritable feast in the midst of the prevailing spiritual famine (Amos 8:11 ). -
