  2. Standing wave ratio - Wikipedia

    en.wikipedia.org/wiki/Standing_wave_ratio

    Voltage standing wave ratio (VSWR) (pronounced "vizwar" [1] [2]) is the ratio of maximum to minimum voltage on a transmission line . For example, a VSWR of 1.2 means a peak voltage 1.2 times the minimum voltage along that line, if the line is at least one half wavelength long.

  3. SWR meter - Wikipedia

    en.wikipedia.org/wiki/SWR_meter

    [1]: 27‑21 The meter or amplifier (not shown) connected to the FWD and REV terminals acts as the required drain resistor, and determines the dwell-time of the meter reading. Interior view of an SWR meter. The three parallel coupled lines are visible. Diodes, capacitors and termination resistors are mounted at the ends of the sense lines.

  4. Mathematical descriptions of opacity - Wikipedia

    en.wikipedia.org/wiki/Mathematical_descriptions...

    An electromagnetic wave propagating in the +z-direction is conventionally described by the equation: (,) = ⁡ [()], where E 0 is a vector in the x-y plane, with the units of an electric field (the vector is in general a complex vector, to allow for all possible polarizations and phases);

  5. Signal reflection - Wikipedia

    en.wikipedia.org/wiki/Signal_reflection

    Impedance discontinuities cause attenuation, attenuation distortion, standing waves, ringing and other effects because a portion of a transmitted signal will be reflected back to the transmitting device rather than continuing to the receiver, much like an echo. This effect is compounded if multiple discontinuities cause additional portions of ...

  6. Slotted line - Wikipedia

    en.wikipedia.org/wiki/Slotted_line

    Figure 1. Waveguide slotted line. Slotted lines are used for microwave measurements and consist of a movable probe inserted into a slot in a transmission line.They are used in conjunction with a microwave power source and usually, in keeping with their low-cost application, a low cost Schottky diode detector and VSWR meter rather than an expensive microwave power meter.

    Examples of estimated bandwidth of different antennas according to the schedule VSWR and return loss by the help of the ANSYS HFSS [1]. Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys.

  9. Reflections of signals on conducting lines - Wikipedia

    en.wikipedia.org/wiki/Reflections_of_signals_on...

    A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
