Optical waveguide structures

The purely bound electromagnetic modes of propagation supported by waveguide structures comprised of a thin lossy metal film of finite width embedded in an infinite homogeneous dielectric have been characterized at optical wavelengths. One of the fundamental modes supported by the structure exhibits very interesting characteristics and is potentially quite useful. It evolves with decreasing film thickness and width towards the TEM wave supported by the background (an evolution similar to that exhibited by the sb mode in symmetric metal film slab waveguides), its losses and phase constant tending asymptotically towards those of the TEM wave. Attenuation values can be well below those of the sb mode supported by the corresponding metal film slab waveguide. Low mode power attenuation in the neighbourhood of 10 to 0.1 dB/cm is achievable at optical communications wavelengths, with even lower values being possible. Carefully selecting the film's thickness and width can make this mode the only long-ranging one supported. In addition, the mode can have a field distribution that renders it excitable using an end-fire approach. The existence of this mode renders the finite-width metal film waveguide attractive for applications requiring short propagation distances and 2-D field confinement in the transverse plane, enabling various devices to be constructed, such as couplers, splitters, modulators, interferometers, switches and periodic structures. Under certain conditions, an asymmetric structure can support a long-ranging mode having a field distribution that is suitable to excitation using an end-fire technique. Like asymmetric slab waveguides. The attenuation of the long-ranging mode near cutoff decreases very rapidly, much more so than the attenuation related to the long-ranging mode in a similar symmetric structure. The cutoff thickness of a long-ranging mode in an asymmetric finite-width structure is larger than the cutoff thickness of the sb mode in a similar asymmetric slab waveguide. This implies that the long-ranging mode supported by an asymmetric finite-width structure is more sensitive to the asymmetry in the structure compared to the sb mode supported by a similar slab waveguide. This result is interesting and potentially useful in that the propagation of such a mode can be affected by a smaller change in the dielectric constant of the substrate or superstrate compared with similar slab structures.

Tri-planar controller motion rehabilitation and exercise platform

A rehabilitation and exercise device for facilitating and limiting motion and biomechanical forces along the horizontal and vertical axes in the saggital, frontal, and transverse planes of the human anatomy. The device consists of an elongated, substantially flat platform with somewhat rounded corners (24). The platform is made of a rigid material to prevent fracturing and bending and is further supported on the bottom surface by central support spines (30) and peripheral support spines (16). The platform provides a decreased slip top surface (10) by utilizing a recessed grid (20). The bottom surface of the platform (12) is configured with a larger diameter central platform attachment extension (28) and smaller diameter peripheral platform attachment extensions (32) which have internal recesses (14) configured at a predetermined set of points to accommodate rigid, somewhat rounded pegs (18) of varying shape and diameter. The peg attachments are secured to the bottom surface of the platform with a peg attachment insert screw (34) which rotates into a heilcoil (26) located in the internal recess. The platform allows specific facilitation or limitation of motion and biomechanical forces along the horizontal and vertical axes depending on the placement of human anatomy on the top surface (10) and peg size and placement on the bottom surface (12) of the platform.
