The Poynting Vector Antenna

The Poynting Theorem states that radiation is a product of the Electric (E) and Magnetic (H) fields of an antenna. The fields must occur simultaneously and have the proper curvature. This is accomplished in the Poynting antenna. A conceptual antenna has two hollow cylinders. A tuning coil resonates with the capacity between the two cylinders, thus developing a high voltage between the cylinders which creates the E field. The cylinders are very short with applied voltage on one end and open on the other. This allows RF current to flow on the cylinder which creates the H field. The two fields are in time phase and are orthogonal, thus satisfying the Poynting Theorem. The shape of the antenna may vary from two flat plates to a Flute configuration, and virtually any shape between. The significance of the Flute is that the shape follows a cosine function allowing both fields to be active along the length of the antenna. The Flute antenna may be tuned (simply by varying the inductance of the tuning coil) over a wide range. One of these has a total length of four (4) feet and may be tuned from 2.5 to 25 MHz with high efficiency (loss of less than 1 dB at the lowest frequency). The +/- 3 dB bandwidth is nominally one tenth (0.1) the operating frequency. Thus Q=10. The radiation pattern is isotropic and the polarization is elliptical. This virtually eliminates fading due to Faraday rotation for HF communications, and at VHF frequencies prevents nulls due to multiple reflections from large buildings. The optimum size of the antenna is typically 3% of a wavelength, but may be less if wide bandwidth is not a design criterion. Because the radiation pattern is isotropic and radiation occurs at the antenna, two (2) or more Poynting Vector antennas may be used to form a directional array while the individual antennas are not affected by mutual coupling of the H fields. The text of the book presents new physics concepts including a mathematical description of Radiation Resistance and suggested changes to Maxwell's Equations. The book will be useful to every Ham operator, all Antenna Engineers, and every person concerned with Physics. Because this is a paradigm shift in antenna technology, the book is an excellent text for a graduate level antenna course.

"Diff in June" tells a day in the life of a personal computer, written by itself in its own language, as a sort of private log or intimate diary focused on every single change to the data on its hard disk. Using a small custom script, for the entire month of June 2011 Martin Howse registered each chunk of data which had changed within the file system from the previous day's image. Excluding binary data, one day's sedimentation has been published in this book, a novel of data archaeology in progress tracking the overt and the covert, merging the legal and illegal, personal and administrative, source code and frozen systematics. Martin Howse (London 1969 - is a programmer, writer, performer and explorer. He is a co-founder of micro-research, a mobile platform for psychogeophysical research with ongoing projects in Berlin, London, Suffolk and Peenemuende. Over the last ten years he has workshopped, performed, lectured and exhibited worldwide.

If you understand basic mathematics and know how to program with Python, you’re ready to dive into signal processing. While most resources start with theory to teach this complex subject, this practical book introduces techniques by showing you how they’re applied in the real world. In the first chapter alone, you’ll be able to decompose a sound into its harmonics, modify the harmonics, and generate new sounds. Author Allen Downey explains techniques such as spectral decomposition, filtering, convolution, and the Fast Fourier Transform. This book also provides exercises and code examples to help you understand the material. You’ll explore: Periodic signals and their spectrums Harmonic structure of simple waveforms Chirps and other sounds whose spectrum changes over time Noise signals and natural sources of noise The autocorrelation function for estimating pitch The discrete cosine transform (DCT) for compression The Fast Fourier Transform for spectral analysis Relating operations in time to filters in the frequency domain Linear time-invariant (LTI) system theory Amplitude modulation (AM) used in radio Other books in this series include Think Stats and Think Bayes, also by Allen Downey.
