Title
Study of Emission from Finite-Size Objects using FDTD
Abstract
A 3D-FDTD algorithm is developed and used to compute the emissivity of finite-size and arbitrary-shape objects. Under thermal equilibrium, the emissivity of an object is the same as its absorptivity. The absorptivity is a function of both the scattering cross section and the absorption cross section of the object; in this study, these cross sections were computed using the FDTD approach. Emissivity values for spherical, cylindrical and landmine-like objects as function of observation angle, polarization and permittivity are generated and presented in this paper.
