Description
Elektronikendüstrisinin büyümesinin ve haberleşme, otomasyon, biyomedikal, uzay ve diğeralanlardaki yaygın kullanımının etkisi birçok elektromanyetik girişim sorununayol açmaktadır. Elektromanyetik girişim bir elektronik cihazın, başka birelektronik cihazdan kaynaklanan, radyo frekansı spektrumunda birelektromanyetik alanın yakınında çalışmasıyla ortaya çıkan bozulmadır. Bubozulma elektronik cihazları etkilediği gibi insan sağlığını da etkilemektedir.Bu nedenle, elektromanyetik girişimin olumsuz etkilerinden etkili bir şekilde korunmaihtiyacı ortaya çıkmaktadır. Bu makalede, yönlendirilmiş yonga levha ile bakır levha karma kompozitmalzeme olarak kullanılmıştır. Yönlendirilmiş yonga levhanın ara yüzeyi ileyüzeyi bakır folyo ile kaplanarak metal kafes oluşturulmuştur. Bakır folyokaplı yönlendirilmiş yonga levhanın 1.88 GHz ile 2.62 GHz ve 5.20 GHz ile 5.62 GHz frekanslarıarasında elektromanyetik soğurma etkinliğinin kabul edilebilir düzeyde olduğugörülmüştür.
The influence of growth of electronics industry andits widespread use in communications, automation, biomedical, space and otherfields leads to many electromagnetic interference problems. Electromagneticinterference is the deterioration of operation of an electronic device when itis in the close neighborhood of an electromagnetic field in the radio frequencyspectrum that is caused by another electronic device. This deteriorationaffects electronic devices as well as human health. Therefore, there is a needto effectively protect against the adverse effects of electromagneticinterference. In this paper, copper board and oriented strand board were usedas a hybrid composite material. The interface and surface of oriented strandboard were coated with copper foil and the metal cage was formed. It was foundthat electromagnetic shielding effectiveness in the frequency range of 1.88 GHz- 2.62 GHz and 5.20 GHz - 5.62 GHz of the oriented copper foil coated orientedparticle board was acceptable.
