An attractive advance in the use of the finite-difference time-domain (fdtd) method has been the introduction of the reduced fdtd (r-fdtd) algorithm, which can reduce computer memory requirement in the storage of the fields by up to 33%. The initial implementation is limited for solving Maxwell equations in isotropic lossless media. This paper introduces an extension of r-fdtd algorithm. The proposed extension uses fdtd formula of Maxwell curl equations to eliminate one component each of E and H. This enables us have a memory-efficient formulation for solving Maxwell equations in homogeneous isotropic lossy media.
