Magnetic Loss in Microwave Heating

Applied Physics Express, 2012
A simplified equation for quantifying magnetic loss in materials under microwave irradiation was derived to demonstrate the importance of magnetic loss in microwave heating. The magnetic losses for five ferrites, namely, BaFe12O19, SrFe12O19, CuFe2O4, CuZnFe4O4, and NiZnFe4O4 were calculated at 2.45 GHz using the derived equation.
