An optical filter is presented based on lateral beam propagation between input and output fibers, through a 1dimensional silicon photonic bandgap (PBG) structure. Optical modelling of the device shows that a very high degree of verticality is needed for the PBG surfaces, and a fabrication technique is described by which these can be obtained, using a combination of wet and dry silicon etching s...

We describe the properties of three families of inversion-symmetric, large photonic band-gap (PBG) template architectures defined by iso-intensity surfaces in four beam laser interference patterns. These templates can be fabricated by optical interference (holographic) lithography in a suitable polymer photo-resist. PBG materials can be synthesized from these templates using two stages of infil...

1098-4402= We present the detailed description of the successful design and cold test of photonic band gap (PBG) resonators and traveling-wave accelerator structures. Those tests provided the essential basis for later hot test demonstration of the first PBG accelerator structure at 17.140 GHz [E. I. Smirnova, A. S. Kesar, I. Mastovsky, M. A. Shapiro, and R. J. Temkin, Phys. Rev. Lett., 95, 0748...

A cellular enzyme linked immunosorbent assay (CELISA) is reported for the detection of circulating polymorphonuclear granulocyte binding immunoglobulin (PBG) in patients' sera. The assay features a solid phase microtiter method in which the enzyme urease is fixed to the antihuman globulin conjugate reagent and uses 0.25 percent glutaraldehyde fixed normal human polymorphonuclear neutrophils (PM...

We have derived the global band gaps for general two-dimensional ~2D! photonic band gap ~PBG! structures formed by square or triangular arrays of metal posts. Such PBG structures have many promising applications in active and passive devices at microwave, millimeter wave, and higher frequencies. A coordinate-space, finite-difference code, called the photonic band gap structure simulator ~PBGSS!...

We demonstrated previously that atrial natriuretic peptide (ANP) enhances reflex bradycardia to intravenous serotonin [5-hydroxytryptamine (5-HT)] (von Bezold-Jarisch reflex) in rats. To determine whether 1) ANP affects this cardiopulmonary vagal reflex in another species and 2) B-type (BNP) and C-type (CNP) natriuretic peptides share with ANP the ability to modulate this reflex, we used intrav...

In this paper, a microstrip patch antenna array on ground with PBG is simulated and measured. It is shown that the photonic band-gap (PBG) can suppress harmonics and optimize the current distribution on the patches. As a result, the gain of the antenna array is improved and the side-lobe level is reduced. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 41: 127–130, 2004; Published onl...

Using symmetry considerations, we identify three families of large photonic band-gap (PBG) architectures defined by the isointensity surfaces of four beam laser interference. For particular choices of beam intensities, directions, and polarizations, we obtain a diamondlike crystal, a novel body-centered cubic architecture, and a simple cubic structure with PBG to center frequency ratios of 25%,...

A RAPID and accurate diagnosis of acute intermittent porp11yri t ( AlP) became possible once suitable methods were available for measurement of urine content of -aminolevulinic acid ( AI A ) and porphobilinogen (PBG).”2 Similarly, in lead poisoning, determination of ALA excretion has proven a useful chemical adjunct, both for diagnostic and therapeutic evaluation.3 The biochemical defect( s ) w...

The modulation of acetylcholine (ACh) release by 5-HT3 receptor activation was studied using in vivo microdialysis. Spontaneous and K+-stimulated ACh release were measured in frontoparietal cortex and hippocampus of freely moving rats. Two consecutive exposures to high K+ produced ACh release of similar magnitude. In the cortex, serotonin (5-HT) failed to alter spontaneous ACh release, but caus...
