Abstract
A field of waveguides is disclosed. A tubular electromagnetic waveguide includes a hollow central portion defined by a first set of at least seven primary hollow tubes that are distributed annually about the hollow central portion, and a second set of tubes including at least one secondary hollow tube; when there are a plurality thereof positioned annularly around the primary hollow tubes the area of the at least one secondary hollow tube is comprised between 0.35 and 0.50 times the area of the hollow central portion. The hollow tubes of the first set are substantially of same size and distant from one another.
Claims20
An electromagnetic waveguide, based on the inhibited-coupling mechanism, comprising:
- a hollow central portion the contour of which is at least partially defined by a first set of at least seven primary hollow tubes, distributed annularly around the central hollow portion, said primary hollow tubes being substantially of the same size and distance from one another;
- including a second set of tubes comprising at least one hollow secondary tube positioned annularly around the primary tubes;
- the area of the at least one hollow secondary tube being comprised between 0.35 and 0.50 times the area of the central hollow portion;
- and
- the first set of at least seven primary hollow tubes comprises a distance (δtt) between two primary tubes, the distance (δtt) being comprised between 800 nm and 2 μm.
