146.	Sjöberg, Daniel (author) Homogenization of dispersive material parameters for Maxwell's equations using a singular value decomposition 2005 In: Multiscale Modeling & Simulation. - : Society for Industrial & Applied Mathematics (SIAM). - 1540-3459 .- 1540-3467. ; 4:3, s. 760-789 Journal article (peer-reviewed)abstract We find effective, or homogenized, material parameters for Maxwell's equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After defining a singular value decomposition of the non-self-adjoint partial differential operator, we expand the electromagnetic field in the modes corresponding to the singular values and show that only the smallest singular values make a significant contribution to the total field when the scale is small. The homogenized material parameters can be represented with the mean values of the singular vectors through a simple formula, which is valid for wavelengths not necessarily infinitely large compared to the unit cell.
147.	Sjöberg, Daniel (author) Homogenization of dispersive material parameters for Maxwell's equations using a singular value decomposition 2004 Reports (other academic/artistic)abstract We ﬁnd effective, or homogenized, material parameters for Maxwell’s equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After deﬁning a singular value decomposition of the non-selfadjoint partial diﬀerential operator, we expand the electromagnetic ﬁeld in the modes corresponding to the singular values, and show that only the smallest singular values make a signiﬁcant contribution to the total ﬁeld when the scale is small. The homogenized material parameters can be represented with the mean values of the singular vectors through a simple formula, which is valid for wavelengths not necessarily inﬁnitely large compared to the unit cell.
