Abstract:To calibrate an electric field prove for evaluating specific absorption rate (SAR) of wireless devices operated in the MHz band, we have proposed the use of circular loop antenna immersed in tissue-equivalent liquid. In our proposed method, near-field gain of the loop antenna should be evaluated to estimate the fields radiated by the loop antenna. However, there is a serious problem that its size which can determined as the near-field gain is constant in its neighborhood is much larger than a liquid container … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
