Guiding and Leakage Dispersion Characteristic of TM01Mode in a Circular Dielectric Rod
Open dielectric waveguide structures such as circular dielectric rods can be used as antennas by leaking energy in the transverse direction or as guiding structures with low loss in integrated circuits at different frequency ranges.

Anisotropic leaky-like perturbation with subwavelength gratings enables zero crosstalk
Electromagnetic coupling via an evanescent field or radiative wave is a primary characteristic of light, allowing optical signal/power transfer in a photonic circuit but limiting integration density. A leaky mode, which combines both evanescent field and

Wide Band Periodic 2D Leaky-Wave Antenna for Millimeter-Wave Application
A wideband periodic leaky-wave antenna (LWA) is proposed in this paper. By using lossy dielectric material inside the wedge-like guide as medium for wave propagation, a leaky mode is excited and results in widening the bandwidth.

Design and fabrication of an all-dielectric grating with top-hat high diffraction efficiency over a broad spectral range [PDF]
Between 98% and 100% flat top efficiency –1st order TE diffraction over a 40 nm wavelength range centered at 800 nm can be obtained by an all-dielectric grating structure where the corrugation is etched in a high index layer unlike in the state of the ...

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

Spontaneous Emission in Leaky Modes of Nanowires
Analytical expressions for spontaneous emission pro-bability in the vicinity of nanowire for the emitter oriented in axial, radial and azimuthal direction in respect to the nanowire axis, has been obtained. Directionality of emission and probability of emission have been calculated for various positions of emitter.
