Ferrit Tabanlı Nanokompozit Malzemelerde Mikrodalga Soğurma Özelliklerinin Araştırılması

Abstract

Today as a result of the developing information and communication technologies the exposed amount of electromagnetic radiation of the mankind is increasing. Also military and civil early warning systems and positioning systems (radars) are using electromagnetic waves to find objects. During past decades generally low frequency (RF) waves have been used for the data communication and also for radars. However today microwave frequencies are preferred due to the needs for high speed data transfer. Similarly at the military positioning systems (radars) microwave frequencies are preferred for high resolution positioning and accuracy. So for the civil and military technologies it is very important to develop microwave absorption materials that are cheap, durable and show high absorption in a broad band range.In the literature there are several materials investigated and used in the microwave range.
