ABSTRACT
Many components for terahertz (THz) optical filtering are mechanically fragile and are hard to produce with large aperture, making them unsuitable for applications where larger THz beam diameter is required. In this work, the THz optical properties of industrial-grade, readily available and inexpensive woven wire meshes are studied using THz time-domain spectroscopy and numerical simulations. These meshes are meter-sized, free-standing sheet materials that are principally attractive for the use as robust, large-area THz components. Our results show that such meshes can act as efficient, tunable THz bandpass filters due to sharp plasmonic resonance supported by the interwoven metallic wires. Further, the meshes that combine metallic and polymer wires act as efficient THz linear polarizers with a polarization extinction ratio (field) above 60:1 for frequencies below 3 THz.
ABSTRACT
Se realizaron correlaciones del IgE total, Phadiatop y anticuerpos IgE específicos contra alergenos en 112 pacientes enviados con el diagnóstico de una patología alérgica. Se encontraron valores bajos de IgE total en promedio de 138 UI/ml. Es estadísticamente significativa que la elevación del IgE total condiciona un test Phadiotop+(P<0,05). Por otra parte se encuentran pacientes con niveles normales o bajos de IgE con presencia de anticuerpos IgE específicos contra alergenos. La concordancia entre phadiotop y RAST EIA IgE+es del 100 por ciento
