Heating of metal powders in the external high-frequency field

This article suggests a method of approximate calculation of microwave heating of the micron-sized metal particles, based on the two limiting cases when the skin depth is much larger than the particle size and when the skin depth is much smaller than the particle size. The calculation was done for spheroidal and ellipsoidal particle shapes. To investigate the spheroidal particles the comparison of the proposed method with the exact solution and with the results of numerical calculation will be completed. The examination of the ellipsoidal particles requires the comparison of the proposed method and the results of the numerical calculation.
