A compact cesium glass cell serving as the microwave magnetic field sensing head was used to measure the spatial distribution of microwave radiation from an open-ended waveguide antenna. The measured microwave magnetic field was not restricted by other microwave devices. The longitudinal distribution of the magnetic field was measured. The experimental results measured by the sensor were in agreement with the simulation. In addition, a slightly electromagnetic perturbation caused by the glass cell was investigated through simulation calculations.<\/jats:p>","DOI":"10.3390\/s18103288","type":"journal-article","created":{"date-parts":[[2018,10,2]],"date-time":"2018-10-02T08:23:50Z","timestamp":1538468630000},"page":"3288","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A Quantum-Based Microwave Magnetic Field Sensor"],"prefix":"10.3390","volume":"18","author":[{"given":"Hao","family":"Shi","sequence":"first","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"},{"name":"School of Astronomy and Space Science, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Ma","sequence":"additional","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaofeng","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shougang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Time and Frequency Standards, National Time Server Center, Chinese Academy of Sciences, Xi\u2019an 710600, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"426","DOI":"10.1109\/94.788738","article-title":"Calculation of calorimetric effect of thermo-field electron emission","volume":"6","author":"Anikeev","year":"1999","journal-title":"IEEE Trans.
