equations, some stationary characteristics are evaluated for different phase-shifted DFB structures in the above-threshold regime, where the corrections due to spatial hole burning must be taken into account. Results show that, while presenting smaller selectivity in the near-threshold regime, the 3

The dominant cost of multiplying the coefJicient matrix resultingfrom the finite-element-boundary-integral analysis of scattering from coated metallic structures is due to the dense submatrices arising from the discretization of the boundary integral. Direct multiplication of these dense submatrices
## Abstract A new __O__(__N__โlogโ__N__) FFTโbased method to expedite matrixโvector multiplies involving multilevel blockโToeplitz (MBT) matrices is presented. The method is also a minimal memory method with __O__(__N__) memory requirements because only nonredundant entries of the MBT matrix are st
