Keywords: Radio Frequency (RF) Laboratory Apparatus (14531317469).jpg Laboratory apparatus for mapping and imaging of radio frequency RF electric fields at resolutions below the usual RF wavelength limit Rubidium atoms are placed in the glass cylinder on the right which is illuminated at opposite ends by red and blue laser beams The cylinder 2 5 by 7 5 centimeters in size moves left on a track to enable the narrow laser beams to scan its entire width The antenna on the left generates an RF field which depending on its frequency has a certain effect on the spectrum of light absorbed by the atoms By measuring this effect researchers can calculate and map the RF field strength as a function of position in the cylinder See also http //www nist gov/pml/electromagnetics/subwave-061714 cfm www nist gov/pml/electromagnetics/subwave-061714 cfm Credit Holloway/NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/14531317469/ Radio Frequency RF Laboratory Apparatus 2014-01-22 11 21 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/14531317469 2016-09-07 01 31 48 United States Government Work Uncategorized 2016 November 8 |
