Absorption analysis of a strip grating placed absorber by themethod of moments

摘要

The method of moments is applied for the calculation of reflectionfrom specially designed microwave absorbers which are different fromconventional ones based on transmission line theory, and non-reflectionconditions are sought. The absorber has periodical arrays of conductivestrips on a lossy material with metal lining on the back surface and isfound to be a new frequency-tuned absorber. It features largeversatility in choosing the lossy material compared to conventionalabsorbers
