Negative refraction is demonstrated in one-dimensional (1D) dielectricphotonic crystals (PCs) at microwave frequencies. Focusing by plano-concavelens made of 1D PC due to negative refraction is also demonstrated. Thefrequency-dependent negative refractive indices, calculated from theexperimental data matches very well with those determined from band structurecalculations. The easy fabrication of one-dimensional photonic crystals mayopen the door for new applications.Comment: 3 pages and 5 figure
