Abstract
Disclosed are relay elements exhibiting transverse localization. The relay elements may include a relay element body having one or more structures, where the structures can be coupled in series, in parallel and/or in stacked configurations. The structures may have multiple surfaces such that energy waves propagating therethrough the relay elements may experience spatial magnification or de-magnification.
Claims20
A device comprising:
- a structure formed of at least first and second component engineered structures, the structure having a first surface and a second surface;
- wherein the first surface has a surface area different than the second surface;
- wherein energy waves propagating between the first surface and the second surface travel substantially parallel to a first direction due to a substantially higher transport efficiency in the first direction than in a second direction;
- wherein the first surface having a first acceptance cone of a first angle and the second surface having a second acceptance cone of a second angle, the first and second angles being relative to the first direction and the first angle being different from the second angle;
- wherein the energy waves propagate between the first surface and the second surface through both the first component engineered structure and the second component engineered structure;
- and
- wherein the substantially higher transport efficiency in the first direction is provided, at least in part, by wave interference limiting the propagation of energy waves in the second direction.

A method comprising:
- providing a structure formed of at least a first component engineered structure and a second component engineered structure, the structure having a first surface and a second surface, wherein the first surface has a surface area different than the second surface;
- propagating energy waves between the first surface and the second surface of the structure through both the first component engineered structure and the second component engineered structure, wherein the energy waves propagated therethrough travel substantially parallel to a first direction due to the structure having a substantially higher transport efficiency in the first direction than in a second direction;
- wherein the first surface having a first acceptance cone of a first angle and the second surface having a second acceptance cone of a second angle, the first and second angles being relative to the first direction and the first angle being different from the second angle;
- and
- wherein the substantially higher transport efficiency in the first direction is provided, at least in part, by wave interference limiting the propagation of energy waves in the second direction.
