Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This paper is devoted to rigorous electromagnetic diffraction analysis, in the near infrared, for micromechanical silicon interdigitated beam gratings with both lateral and vertical displacement of movable beams. In the wavelength-to-period ratio domain where the gratings support three diffraction orders, the specific designs of high-efficiency switches for polarized radiation, such as switches from a transmitter to a 1 × 3 transmission beamsplitter and from a retroreflector to an 1 × 2 reflection beam divider, are presented. The possibility of light modulation, which follows from these designs, is discussed. The analysis with respect to wavelength, beam-width, beam-height, and incidence-angle variations shows a good tolerance of the devices' performance to spectral shifts and to fabrication and mounting errors. In addition, with the use of our software we simulated the diffraction efficiency versus displacement at a visible wavelength for a micromechanical grating reported in the literature. There is good agreement between theory and experiment. © 1999 Society of Photo-Optical Instrumentation Engineers.
