Abstract

ABSTRACT

There is a necessity of tissue equivalent (phantom) models in research of electromagnetic (EM) effects in biologic tissues. Recently, many kinds of tissue models depend on the different aim were proposed. So many studies were carried on the interaction of human-head and cellular phone. The most of them are related to numerical models. Owing to difficulty of study on human body, simulation of human tissues is required. In this study two different, for 900MHz and for 1800MHz, brain equivalent tissues have been prepared and their electrical features were evaluated by taking into consideration of mixing rates.

Abstract

Biyolojik dokularda elektromanyetik (EM) etkilerin araştırılması için doku eşdeğer modellerine gereksinim duyulmaktadır. Son zamanlarda bu amaçla değişik araştırmalara yönelik doku modelleri önerilmektedir. Cep telefonları ve insan kafası etkileşimi üzerine çok fazla araştırma yapılmaktadır. Bu araştırmaların çoğunluğu sayısal model çalışmalarından oluşmaktadır. İnsan üzerinde deneysel çalışmaların zor olması nedeniyle biyolojik dokuların simüle edilmesi gerekmektedir. Bu çalışmada 900MHz ve 1800MHz için iki ayrı beyin eşdeğer dokusu hazırlanmış ve karışım oranları dikkate alınarak elektriksel özellikleri belirlenmiştir

Keywords

Beyin eşdeğer dokusu, RF soğurulma, GSM, Fantom model
