Question

Table the Six " Fe alloy based composites for microwvae absorbance" which are used for Fe/carbon based microwave and RF electromagnetic waves absorbance. List all the SIX materials by their compound, preparation method, thickness and frequency.

Note: This belongs to a PhD Physics subject review question paper on the topic of Fe and Oxygen based Perovskite for applications in Nanomagnetism and electromagnetic interference, if you dont have perfect knowledge in this area, please do not attempt.

Answer 1

Six " Fe alloy based composites for microwave absorbance applications:

1.  

Method = Solvothermal : Thickness = 5.89 mm : Frequency = 2.02 GHz

2.

Method = Electrodposition : Thickness = 2.02 mm : Frequency = 1.5 GHz

3.

Method = Hydrothermal   : Thickness = 1.5 mm : Frequency = 5.5 GHz

4.

Method = Two-step electrodeposition : Thickness = 2.00 mm : Frequency = 0.03 GHz

5.

Method = Two step reaction : Thickness = 3 mm : Frequency = 18 GHz

6.

Method = Acid treatement: Thickness = 2.5 mm : Frequency = 8-12 GHz
