    "abstract": "We have measured the photonic bandgap in the transmission of microwaves\nthrough a two-dimensional photonic crystal slab. The structure was constructed\nby cementing acrylic rods in a hexagonal closed-packed array to form\nrectangular stacks. We find a bandgap centered at approximately 11 GHz, whose\ndepth, width and center frequency vary with the number of layers in the slab,\nangle of incidence and microwave polarization.",
