The term also applies to guided waves in solids.
In addition, the underlying physics of guided waves is more complex than bulk waves.
Since then, there has been an increased effort on the analytical study of guided wave propagation in cylindrical structures.
Waves in plates were among the first guided waves to be analyzed in this way.
The guided wave on the uniform structure is a fast wave, and thus radiates as it propagates.
But Maxwell's equations do lead to the appearance of longitudinal waves under some circumstances, for example, in plasma waves or guided waves.
IEEE microwave and guided wave letters.
Guided wave testing uses very low ultrasonic frequencies compared to those used in conventional UT, typically between 10 100kHz.
One table is for both open region (radiation and scattering problems) and another table is for guided wave problems.
Guided wave testing (GWT)
Guided Wave testing (GWT) is one of latest methods in the field of non-destructive evaluation.
The study of guided waves propagating in a structure can be traced back to as early as the 1920s, mainly inspired by the field of seismology.

The post-wall waveguide is known to have similar guided wave and mode characteristics to the conventional rectangular waveguide with equivalent guided wavelength.
As a rule of thumb, the width of a waveguide needs to be of the same order of magnitude as the wavelength of the guided wave.
Waveguides are the fundamental principle of guided wave testing (GWT), one of the many methods of non-destructive evaluation.
From a more sophisticated point of view, the periodic modulation creates a guided wave that consists of an infinite number of space harmonics (Floquet modes).
Mechano-optical modulators, in which a mechanical element such as a cantilever or clamped-clamped beam perturbs the optical evanascent field of a guided wave.
EMAT provide a convenient means of generating SH bulk wave and SH guided waves.
Experimental programs include the fabrication of micro-structured guided-wave optical devices and studies of nonlinear optical effects in periodic guided wave geometries.
The journal was established in 1999 as IEEE Microwave and Guided Wave Letters and obtained its current title in December, 2000.
For more accurate modelling involving multiple reflections, head waves, guided waves and surface waves, as well as transmission effects and geometrical spreading, full waveform modelling is required.
Professor Allan Boardman is known for his work on surface plasmons and guided wave optics, especially nonlinear waves, solitons, magneto-optics and negative refracting metamaterials.
There is also an extensive reference list that is focused on the properties of artificial dielectrics in the 1990 book, Field theory of guided waves by R. E. Collin.
Excitation of the guided wave by an incident beam can also be viewed as a problem in coupled modes, the modes being the waveguide mode and a representation for the incident beam.
