SCIENCE HOBBYIST | WEIRD DIY | GOOD STUFF | NEW STUFF | SEARCH Notes on Scalar Detector Designs (c)1996 Robert Shannon Detector specifications Magnetostatic Detectors Electrostatic Detectors Barkhausen Detector Detector Schematic GIFs & JPEGs In this document we will describe the characteristics and specifications of several different scalar detector designs, and how the design philosophy and technology chosen affects those specifications. We will compare and consider these designs in ord er to establish a basic framework of specifications used to classify existing scalar detector designs, and suggest new modifications and original designs. We will discuss the Hodowanec "Gravity Wave Detector" circuit, and some suggested modifications, along with "Bedini's version" of the Dea/Faretto scalar detector, and compare these quite different designs, as well as an original detector design, the Barkhausen Effect Detector. Scalar detectors can be classified by the translation mode used, the bandwidth of the signal to which the detector will respond, and whether the response of the detector is linear with respect to the applied scalar signal or not. Some scalar detector s may also produce secondary scalar signals in their operation, so we may also classify detectors as being either passive or active detectors. All of these broad classifications, as well as other specifications such as relative sensitivity may vary in d ifferent detector designs. These criteria may be used to describe and compare different scalar detector designs. The translation mode by which the scalar signal is translated into an electromagnetic signal will largely determine the overall specifications of any detector design. This provides us with a convenient starting point for the analysis of the design o f any practical scalar detectors. When analyzing any new design for a scalar detector, the first step is to determine what translation mode or modes are being used by the device. We may classify a given detector as using either magnetostatic or electros tatic translation modes, or some combination of both. A reference design for a simple scalar pulse generator will also be presented so that each detector may be evaluated with a standard signal source. Suggested modifications will allow experimenters to produce a range of signals for comparative detector evaluation. Detector specifications : Translation Mode - There are several known modes of translation, that is, the exchange between electromagnetic waves and scalar potentials. In the context of detectors, we are most interested in translation by magnetic and electrostatic modulatio n. In the case of magnetic modulation, we may observe a scalar signal modulating a fixed magnetic field. In electrostatic modulation, we might observe alterations in the parameters of dielectrics in response to a scalar stimuli. We can classify the translation mode for detectors as being either ( E ), for electrostatic, ( M ) for magnetostatic, or ( B ) for both. This might be a bit confusing, as B is also used to represent the magnetic field in other co ntexts. Frequency and Bandwidth - We can express the frequency response of a scalar detector in the same manner used for an electromagnetic device. Some detectors may have a variable frequency over some specified range. In the table below we describe the range over which this type of design is practical, not the range of a single device of that type. Linearity - A linear detector produces a duplicate electromagnetic copy of an incident scalar signal, while nonlinear detectors produce a signal that is not proportional to the input stimuli. Active / Passive - Detectors that produce a scalar signal in the process of detecting an incident scalar signals are said to be active, while others that produce no internal scalar potential are passive. Sensitivity - Because no accepted standard units exist, and different detector designs may react to different degrees to a range of scalar stimuli, it is not possible to express the sensitivity of a given scalar detector design in simple units . Sensitivity may be evaluated by measuring the maximum distance a given stimuli can be detected. Because different detectors prefer differing types of signals, direct evaluation is only possible if we express sensitivity simply as excellent, good, fair, and poor.
