WAVEFORM ANALYSISObservation displays of voltage and current variations with respect to time or by harmonic analysis of complex signals [16]. |
WAVEFRONTA small section of an expanding sphere of electromagnetic radiation that is perpendicular to the direction of travel of the energy [10]. |
WAVEGUIDEA rectangular, circular, or elliptical metal pipe designed to transport electromagnetic waves through its interior [10] [11]. |
WAVEGUIDE DUPLEXERTR and atr tubes housed in a resonant cavity attached to a waveguide system. |
WAVEGUIDE MODE OF OPERATIONAny particular field configuration in a waveguide that satisfies the boundary conditions. Usually divided into two broad types: the transverse electric (TE) and the transverse magnetic (TM) modes [11]. |
WAVEGUIDE POSTA rod of conductive material used as impedance changing devices in waveguides [11]. |
WAVEGUIDE SCREWA screw that projects into a waveguide for the purpose of changing the impedance [11]. |
WAVELENGTHThe distance, usually expressed in meters, traveled by a wave during the time interval of one complete cycle. It is equal to the velocity divided by the frequency [2] [10] [12]. |
WAVEMETERSCalibrated resonant circuits that are used to measure frequency [16]. An instrument for measuring the wavelength of an RF wave [18]. |
WEBER'S THEORYA theory of magnetism which assumes that all magnetic material is composed of many tiny magnets. A piece of magnetic material that is magnetized has all of the tiny magnets aligned so that the north pole of each magnet points in one direction [1]. |
