Recently PGB (photonic band gap) filters show a great
development. Here we will present two different PGB filters with
lattice etched in the ground plane. The rejection band characteristic
is function of the number and shape of elements etched. Th
ese
filters are modelling by the FWCIP method.
Novel rejected and passed band devices are obtained using
techniques in two dimensional Photonic Band Gap microstrip
structures. The microstrip is engraved in a PBG dielectric
constituted of a via holes array and enclosed in a metallic box. The
b
oundary element method (BEM) and the fast wave concept
iterative process (FWCIP) are combined to evaluate the
characteristic of this structure.
Quality Control procedure Of Gamma Spectrometry measurements using
semi conductor HPGe Detectors and determination the uncertainty budget of
the measurements and calibrations have been prepared.
Depending on this procedure we can evaluate the qual
ity of the results to be
accepted or not, and where the correction actions should be used.
