A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
Characterization of the Ga-InSb system: experimental investigation of thermal, structural, mechanical and electrical properties
(National Institute of Optoelectronics, 2015)
The materials based on gallium-antimonide are widely used in electronic industry in the production of various electronic devices. The results of characterization of selected alloys in the Ga-InSb system obtained by ...
Far infrared and photoacoustic characterization of iodine doped PbTe
(National Institute of Optoelectronics, 2012)
Single crystal samples of PbTe doped with PbI2 were made using the Bridgman technique. Far infrared reflectivity diagrams of PbTe doped with 0.4 at% and 0.6 at% Iodine were measured and numerically analyzed. A plasma ...
Far infrared properties of PbTe doped with Hg
(National Institute of Optoelectronics, 2010)
Single crystal samples of PbTe doped with Hg were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with 0.5 at. % Hg; 0.9 at. % Hg and 1.4 at. % Hg. The plasma ...
The comparative study of Nd-Fe-B magnetic materials with different Nd content
(National Institute of Optoelectronics, 2009)
For the purpose of better understanding of the effect of different Nd content on the magnetic properties of three types of commercial Nd-Fe-B alloys with 10-12 wt% Nd (Nd-low), 21-25 wt% (Nd-stoich.), and 26-29 wt% Nd ...
