Özet:

 


Electrical shielding
effectiveness (ESE) has become a popular research topic after EM waves have
begun to be used in our everyday lives. Although the absorption and reflection
of electromagnetic energy are those two basic methods used, the efficient techniques
used in shielding are based on suppressing the reflection of EM waves and
increasing the absorption of energy. This study has focused on BaTiO3-ethanol
nano–fluid as an absorber. Absorbing fluid/material was prepared by means of
magnetic stirring, heating and ultrasonic bathing methods then the tubings that
is going to behave as shielding screen (SS) were filled with this nano–fluid material.
Transmission Line Method (TLM) was preferred to obtain reflection, transmission
and absorption coefficients of ESE by means of S11 and S21.
Fluid speed and its temperature have a potential to change the performance of
ESE that it has been observed that increasing flow rate from 0 ml/min to 500
ml/min results in 12% increase in shielding effectiveness at low fluid
temperature (300C). In the second case which measurements repeated
at high fluid temperature (600C) it is seen that 1.05% increase in
shielding effectiveness while flow rate increased from 0 ml/min to 500 ml/min.
