Integrated multicolor detector utilizing 1-D photonic bandgap filter with wedge-shaped defect
(Society of Photo-Optical Instrumentation Engineers (SPIE), 1999)
Abstract
We propose a single-chip multicolor photodetector for (3-5) μm range based on a linear IR semiconductor detector array with an integrated 1-D photonic bandgap (PBG) filter. A wedge-shaped defect slab (corresponding ...
Numerical calculation of photodetector response time using Ramo's theorem
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
The work presents a methodology for numerical calculation of response time of p-i-n photodiodes using the corpuscular approach, i.e. the Ramo's theorem. The calculations were performed for the Si p-i-n photodiode homostructure ...
Ceruloplasmin, copper and zinc in pulmonary emphysemia
(Bulgaria : Balkan Federation of Clinical Laboratory, 1996)
We analyzed the blood samples from 20 patients with global respiratory failure (10 males, mean age 56±7 yrs. and 10 females, mean age 60±5 yrs.). All patients were heavy cigarette smokers, in average 33±8 pack-years.

Za analizu korišćeni su uzorci venske krvi pripremljenih sa dodatkom ACĐ rastvora i hloralhidrata i do upotrebe čuvani na <4°C. Standardni rastvori acetaldehida su pripremljeni razblaživanjem standardnog rastvora acetaldehida ...
The influence of selenium on the erythrocyte metabolism in rats exposed to toluene. I Synthesis of unusual hemoglobin modifications
(Timisoara, Romania : Publishing House "Mirton" Timisoara, 1995)
In this work unusual hemoglobin modifications were detected in hemolysates of experimental animals exposed to toluene. The protective effect of selenium administration against hemoglobin structural alterations was investigated ...
Silicon UV flame detector utilizing photonic crystal
(Society of Photo-Optical Instrumentation Engineers, 1999)
Abstract
In this paper we propose a silicon UV flame detector for combustion systems. In gas burners the relative intensity of flame radiation is dominant in the ultraviolet region (below 0.35 μm). In the visible and ...
One dimensional Si-SiO2 photonic crystal with defects intended for use in infrared spectral region
(Institute of Electrical and Electronics Engineers (IEEE), 1997)
Abstract
Based on our detailed theoretical analysis we fabricated 1D Si/SiO2 photonic crystals with donor and acceptor defects. We observed their photonic band-gaps and defect modes by measuring the infrared transmission ...
