Propagation and filtering characteristics of two dimensional (2D) pillar-type photonic crystal waveguide with triangular lattice were simulated by CIP method. The simulation results for Y-shaped branch and the cascaded 1X4 Yshaped branch waveguide were compared with measurements by using a scale model in microwave frequency range from 3.6 to 4.2 GHz. The resonant characteristics for cavities with...
A novel hybrid FRP–concrete structural system is proposed in this paper. CFRP sheets with high strengths are axially bonded on the bottom surface of the concrete core to carry tensile load while GFRP sheets with high rupture strains are hoop-directionally wrapped to bear the shear load. The GFRP sheets also provide confinement to concrete core and prevent premature debonding of CFRP sheets. A minimum...
