The influence of growth of electronics industry and
its widespread use in communications, automation, biomedical, space and other
fields leads to many electromagnetic interference problems. Electromagnetic
interference is the deterioration of operation of an electronic device when it
is in the close neighborhood of an electromagnetic field in the radio frequency
spectrum that is caused by another electronic device. This deterioration
affects electronic devices as well as human health. Therefore, there is a need
to effectively protect against the adverse effects of electromagnetic
interference. In this paper, copper board and oriented strand board were used
as a hybrid composite material. The interface and surface of oriented strand
board were coated with copper foil and the metal cage was formed. It was found
that 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 oriented
particle board was acceptable.

Elektronik
endüstrisinin büyümesinin ve haberleşme, otomasyon, biyomedikal, uzay ve diğer
alanlardaki yaygın kullanımının etkisi birçok elektromanyetik girişim sorununa
yol açmaktadır. Elektromanyetik girişim bir elektronik cihazın, başka bir
elektronik cihazdan kaynaklanan, radyo frekansı spektrumunda bir
elektromanyetik alanın yakınında çalışmasıyla ortaya çıkan bozulmadır. Bu
bozulma elektronik cihazları etkilediği gibi insan sağlığını da etkilemektedir.
Bu nedenle, elektromanyetik girişimin olumsuz etkilerinden etkili bir şekilde korunma
ihtiyacı ortaya çıkmaktadır. Bu makalede, yönlendirilmiş yonga levha ile bakır levha karma kompozit
malzeme olarak kullanılmıştır. Yönlendirilmiş yonga levhanın ara yüzeyi ile
yüzeyi bakır folyo ile kaplanarak metal kafes oluşturulmuştur. Bakır folyo
kaplı yönlendirilmiş yonga levhanın 1.88 GHz ile 2.62 GHz ve 5.20 GHz ile 5.62 GHz frekansları
arasında elektromanyetik soğurma etkinliğinin kabul edilebilir düzeyde olduğu
görülmüştür.
