Zero Frequency

We introduce a metamaterial based parallel-plate waveguide, devised in microstrip technology that features two electromagnetic band-gaps. Since one of the band-gaps extends from zero frequency, the structure can be used as a band-pass filter. We perform a parametric study in view of facilitating design and optimisation.

Initial Viscosity

Aqueous solutions of a 1 weight-per cent poly (ethylene oxide) (PEO) were degassed under vacuum, transferred to a parallel plate viscometer under a nitrogen gas blanket, and exposed to Co60 gamma radiation. The Co60 source was rated at 4000 curies, and the dose ratewas 3.8x105 rads/hr. The poly (ethylene oxide) employed in the irradiations had an initial viscosity average molecular weight of 2.1 x 106.The solutions were gelled by a free radical reaction with dosages ranging from 5x104 rads to 4.8x106 rads.
