- Abstract
- The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength
removes from the incident radiation exactly twice the amount of power it can intercept by its geometrical cross section
area. In this paper, the extinction paradox is generalized to include temporally dispersive material parameters with finite
values of the permittivity and the permeability. From a time-domain approach it is shown that the high-frequency
limit of the extinction cross section depends on the material parameters of the target and that a limiting value not necessarily
exists. These findings are exemplified by several numerical illustrations with different values of the... (More) - The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength
