WebEfficient light coupling between two waveguides inside an optical circuit can be done with a waveguide taper. The coupling efficiency can be controlled via the taper length and shape. The EME solver is ideally suited to characterizing these devices. ... Transmission through a waveguide taper increases as its length increases. For a fixed taper ... All electromagnetic waves consist of electric and magnetic fieldspropagating in the same direction of travel, but perpendicular to each other. Along the length of a normal transmission line, both electric and magnetic fields are perpendicular (transverse) to the direction of wave travel. This is known as the … See more When functioning as transmission lines, though, waveguides are considerably simpler than two-conductor cables—especially coaxial cables—in their manufacture and maintenance. With only a single conductor … See more Signals are typically introduced to and extracted from waveguides by means of small antenna-like coupling devices inserted into the waveguide. Sometimes these coupling … See more Just as transmission lines are able to function as resonant elements in a circuit, especially when terminated by a short-circuit or an open … See more
