We present an improvement over the Wang-Teter, Perrot, and Smargiassi-Madden kinetic-energy functionals without going beyond linear-response theory and without introducing a density-dependent kernel. The improved functionals were tested on bulk aluminum, and excellent results were obtained. Accurate density-functional calculations using the new functionals on systems larger than one can study by traditional Kohn-Sham methods are demonstrated.
