Acoustic resonant leaky mode effects
Applied Physics Letters, 2009An acoustic leaky mode resonator having a structure similar to that of an optical guided-mode resonator is demonstrated experimentally and theoretically. The measured transmission spectra reveal the existence of resonant modes and agree with the predictions of finite-difference time-domain calculations.

Leaky modes in graded index optical fibers
Applied Optics, 1976Leaky mode attenuation coefficients for graded index optical fibers are derived using the WKB approximation. For the case of a parabolic index profile, the attenuation coefficients for explicitly evaluated and used to calculate the leaky mode contribution to near field and attenuation measurements.

Leaky Modes in Nonlinear Optical Resonators
2000The aim of this lecture is to show that leaky modes provide a convenient mean for the study of nonlinear optical interactions in “open” resonators such as Fabry-Perot’s, multilayer structures, prism or grating couplers, etc.

What Is a Quantized Mode of a Leaky Cavity?
2001Quantum optics conventionally represents the electromagnetic radiation in a leaky cavity by a normal-modes expansion, as if the cavity were closed and perfect, with the leakage being described by coupling these modes to a reservoir. This phenomenological approach is only a good approximation for stable resonators with very large quality factors.

Leaky Quasi Modes in Curved Plates
AIP Conference Proceedings, 2005Cylindrical engineering structures can sometimes be inspected effectively using a circumferential guided wave technique to cover the full circumference from a single location. Many of these structures are embedded so that energy leaks into the surrounding material as the waves propagate around the structure.

On resonance widths of leaky Lamb modes
The Journal of the Acoustical Society of America, 1995For an elastic plate immersed in a lossless fluid, it is known that resonances of leaky Lamb modes contribute to the transmission coefficient in a manner dependent on the resonance widths. Based on numerical solutions in the complex wave-number field, an examination of such resonance widths is presented here.

Leaky mode dispersions of Goubau lines
Microwave and Optical Technology Letters, 2007AbstractThe leaky dispersion characteristics of a Goubau line were numerically investigated for three lower‐order transverse magnetic (TM) modes by determining a complex propagation constant using Davidenko's method. As a result, physically meaningful spectral ranges of leaky modes were found to exist below the cutoff frequency of the Goubau line ...
