Leaky Modes of Symmetrical Groove Guide

MTT-S International Microwave Symposium Digest, 2005
Both the odd and even higher modes of groove guide, a low-loss waveguide proposed some years ago for millimeter wavelengths and of interest again today, are investigated quantitatively. We verified an early prediction that all the odd higher modes leak, and we find that all even higher modes do also.

Leaky modes on circular optical waveguides

Applied Optics, 1976
A nonabsorbing optical waveguide of circular cross section supports leaky modes in addition to the well-known bound modes. The detailed properties of these leaky modes are determined by solving the eigenvalue equation for the modes of a circular dielectric cylinder below their cutoff frequency.

Leaky modes on W-fibers: mode structure and attenuation

Applied Optics, 1977
The mode structure of a W-fiber has been discussed in conjunction with that of an SC-fiber using the WKB approximation, and the leaky mode attenuation coefficient has been derived using Poynting's vector theorem. Furthermore, a simplified expression for the attenuation coefficient of the W-fiber has been obtained and compared with that of the SC-fiber.

Liquid level sensing based on leaky mode attenuation in a guided-mode–leaky-mode–guided-mode fiber structure

Optics Communications, 2014
Abstract A liquid level sensing scheme based on leaky mode attenuation and a corresponding liquid level sensor based on a guided-mode–leaky-mode–guided-mode (GLG) fiber structure are proposed, which aim at the liquid whose refractive index (RI) is higher than that of the silica fiber.

Acoustic resonant leaky mode effects

Applied Physics Letters, 2009
An 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.

Microstrip leaky-mode antenna array

IEEE Transactions on Antennas and Propagation, 1997
The first-pass design of a linear eight-element microstrip leaky-mode antenna array is proposed, built, and tested, showing a gain of 18.5 dB, directivity of 23.5 dB, and pencil beam with 3-dB beamwidth (Az/El) of 10.2/spl deg//14.3/spl deg/. Excellent agreement between the theoretical prediction and measured results for the array antenna performance ...

Leaky-mode resonant reflectors with extreme bandwidths

Optics Letters, 2010
We present ultrawide flat-band reflectors enabled with multilevel resonant leaky-mode structures. The reflectors are designed using particle swarm optimization. We show that three-level silicon-on-insulator structures provide bandwidths of approximately 840 nm for TE polarization and approximately 835 nm for TM polarization, across which reflectance is
