Technique for reducing surface wave at an air/left‐handed medium (LHM) interface or excitation of the forward wave in an LHM
Bibliographic record
Abstract
Abstract In this article, we analyze the illumination by an electromagnetic wave of an air/left‐handed medium (LHM) interface. It is shown that by placing a periodic structure of resistors near the LHM it is possible to suppress or to reduce the surface wave that is present at the interface. For our demonstration, we consider a semi‐infinite lossless left‐handed medium having the same constitutive parameters as those of air but with opposite signs. Numerical results, obtained by using a full‐wave time domain technique, are presented to validate our approach and the proposed scheme. This work can extend the potential applications of left‐handed materials, because it shows that it is possible to use LHM slabs having large width. In addition, this work shows that it is possible to excite the forward wave of an LHM instead of the backward wave. © 2008 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
