guide wavelength

[′gīd ¦wāv‚leŋkth]
(electromagnetism)
Wavelength of electromagnetic energy conducted in a waveguide; guide wavelength for all air-filled guides is always longer than the corresponding free-space wavelength.

It should be mentioned that the slot is nonresonant at the work band and its length is more than half a guide wavelength. The reflection coefficient Sn and peak realized gain of Ant.
It means when [l.sub.2] is about [[lambda].sub.g]/4 ([[lambda].sub.g] is guide wavelength), two current nulls will occur at both sides of the resonance.
1.4 x 1.6 2 Ours 93 1.1 x 1.2 1 [[lambda].sub.g] is the guide wavelength at the centre frequency of the work band.
Therefore, the operating mode of the T-shaped waveguide should be analyzed and a rectangular waveguide with the same guide wavelength is proposed for comparison.
The operating center frequency of antenna array is 35 GHz and the guide wavelength [[lambda].sub.g] is set as 15.02 mm.
The perimeter of the conductor annulus with radius [R.sub.0] in the middle layer equals to 1.5[[lambda].sub.g], and [[lambda].sub.g] = 70 mm is the guide wavelength for the SICL at 2.3 GHz.
It is important that the radiator spacing is not a multiple of half a guide wavelength so that reflections from the radiators have a different phase at the feed input and tend to cancel each other.
Here radiators are deliberately spaced a multiple of half a guide wavelength apart to produce a broadside pointing beam.
c = light velocity [[Lambda].sub.g] = guide wavelength L = the length of resonator
Since for sufficiently separated discontinuities (more than one-fifth of the guide wavelength), all evanescent higher-order modes are adequately decayed, this prudent approach is accurate for the most common structures.
Since the guide wavelengths change from step-to-step, this type of inhomogenous transformer is difficult to design by using the transmission-line theory.
