Reinventing gravity : a physicist goes beyond Einstein by John W Moffat( Book )

17 editions published between 2008 and 2015 in 3 languages and held by 729 WorldCat member libraries worldwide

Arguing that Einstein's relativity and the theory of quantum mechanics are fundamentally incompatible, an introduction to the author's modified gravity theory traces recent work in string theory and quantum gravity while revealing how MOG explains the universe's behavior without relying on invisible dark matter
Cracking the particle code of the universe : the hunt for the Higgs Boson by John W Moffat( Book )

11 editions published between 2013 and 2014 in English and held by 503 WorldCat member libraries worldwide

An insider's behind-the-scenes look at the arcane, fascinating world of theoretical and experimental particle physics leading up to the recent discovery of a new boson. If the new boson is indeed the Higgs particle, its discovery represents an important milestone in the history of particle physics. However, despite the pressure to award Nobel Prizes to physicists associated with the Higgs boson, John Moffat argues that there still remain important data analyses to be performed before uncorking the champagne. --Publisher's description
Gain measurement of a cavity-backed spiral antenna from 4 to 18GHz using the three-antenna method by Defence Research Establishment Ottawa( Book )

3 editions published in 1998 in English and held by 4 WorldCat member libraries worldwide

Presents results of the measurement of the maximum gain of a cavity-backed spiral antenna using the three antenna method over the 4-18 gigahertz range. The method was extended to obtain the circularly polarized co- and cross-polarization gain of the antenna under test. This method required the use of two other linearly polarized (LP) antennas (quad-ridged horns). Two sets of gain measurements were performed using the LP antennas with their polarization oriented horizontally then vertically. The report also describes the three-antenna method algorithm, the MATLAB program written for this application, and the experimental steps and procedures required to implement the method. Program listings are appended
Optical alignment of the spherical antenna measurement system by Defence Research Establishment Ottawa( Book )

3 editions published in 1997 in English and held by 4 WorldCat member libraries worldwide

Describes a custom designed system and novel techniques developed to perform a precision alignment of a microwave antenna measurement range using optical instrumentation. The system is an indoor spherical test range located in an anechoic chamber. The alignment hardware consists of several levels, an electronic theodolite with built-in autocollimation capability, and a unique target mirror assembly with the target viewable from both sides. A hand-held programmable calculator is used to calculate angular positions and distances. The instrumentation allows convenient measurement and monitoring of both the range alignment and the orthogonality and intersection of the multi-positioner spherical system axes. Numerous techniques and procedures developed for optical alignment are detailed, with step-by-step instructions to guide the user toward a precise optical alignment. The appendix includes a listing of a program for processing the theodolite readings and description of a technique to measure the phase centre of an antenna
Ice floe and wind velocities in Robeson Channel, 1972( Book )

1 edition published in 1975 in English and held by 3 WorldCat member libraries worldwide

Ice velocities calculated from ice drift measurements in Robeson Channel in 1972 and measured wind velocities are presented and discussed. (Author)
Evaluation of Rotman lenses for space-based radar by John W Moffat( Book )

3 editions published between 1995 and 1996 in English and held by 3 WorldCat member libraries worldwide

A Rotman lens is a bidirectional electrical lens which, together with an array antenna, is capable of generating a discrete number of radiated beams simultaneously, each having a predefined direction in space. This report describes a project that designed, constructed, and tested Rotman lenses for a proposed space-based radar facility. The five Rotman lenses manufactured for the project were found to have unsatisfactory performance, and the report details the ultrasonic and x-ray inspection of the lenses, the metallographic inspection of one of the lenses which was sectioned to confirm the results of the ultrasonic inspection, and the electrical evaluation of the lenses that used a two transmission line method to measure their effective permittivity. The report also discusses the physical mechanisms that could have affected lens performance and the usefulness of ultrasonic inspection for testing microwave stripline circuits
Einstein wrote back : my life in physics by John W Moffat( Book )

3 editions published between 2010 and 2012 in English and held by 2 WorldCat member libraries worldwide

Taking readers inside the classrooms and minds of these giants of modern science, Moffat affectionately exposes the foibles and eccentricities of famous physicists, as they worked on the revolutionary ideas that, today, are the very foundation of modern physics and cosmology
An Antenna Array System for Target Simulation in the DREO Electronic Warfare Engagement Simulation Facility by John W Moffat( Book )

1 edition published in 1986 in English and held by 1 WorldCat member library worldwide

In the Electronic Warfare Engagement Simulation Facility at Defence Research Establishment Ottawa, arrays of equally spaced dipole radiating elements are installed in an RF anechoic chamber and are used to simulate the azimuth and elevation position of radar targets and jammers. This report presents the design, construction, assembly, and final testing of two new arrays of 256 and 16 elements, installed to augment the capability of an existing 64 element dipole array. Special attention has been given to design and construction details which maximize the bandwidth, flexibility, and maintainability of the array system. A key component is a novel RF switching matrix permitting the realization of virtual elements, one between each pair of real elements, thus doubling the target position resolution obtainable from the real elements alone
Radar Position Data Reduction Programs for the Xerox Sigma 9( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

Computer programs for the organization and preliminary reduction of radar position data are described. The basic functions served by the programs are checking the position data for errors and writing the corrected data on magnetic tape, plotting the position data stored on magnetic tape using the Calcomp plotter, calculating the down and cross-channel velocity components from the position tape file data, and writing them on a second magnetic tape; and, plotting the velocity components using the Calcomp plotter.
