Abstract
Resistance to heat was simulated and measured in a computer model as an annihilation of the elastic stress arising from the electric field in the radiation. The elastic stress created from the electromagnetic wave was superimposed with the elastic stresses produced by the rotation of a grain, which was represented in two dimensions as an ellipse in the simulation. Both the tilt angle of the grain with respect to the applied force and the aspect ratio of the grain were varied in the computer program. Results are reported here for a ratio of wavelength to total grain length of 10. Annihilation of an elastic stress from the electric field of up to 80 to 90 percent was seen for aspect ratios of 8/7 to 2 in several ranges of grain tilt angle. For this same range in aspect ratio, steep transitions in the amount of annihilation were seen near the ends of the grain. An elongated grain, with an aspect ratio of 10 and rotating counterclockwise, exhibited extinction of 50 to nearly 90 percent of the electric field near the lower end of the grain throughout the tilt angle range of 5° to 85°.
