Environmental risk assessment of radioactivity and heavy metals in soil of Toplica region, South Serbia
(Springer, 2018-03-13)
Activity levels of natural and artificial radionuclides and content of ten heavy metals (As, Cd,
Co, Cr, Cu, Mn, Ni, Pb, Zn and Hg) were investigated in 41 soil samples collected from Toplica region located in the south ...
Influence of mode coupling on three, four and five spatially multiplexed channels in multimode step-index plastic optical fibers
(Elsevier, 2018-04-04)
We investigate the influence of mode coupling on space division multiplexing capability of three multimode step-index plastic optical fibers with different strengths of mode coupling. Results show that mode
coupling ...
Enhanced bandwidth of W type plastic optical fibers designed from singly clad step index plastic optical fibers
(Elsevier, 2018-11-02)
We propose a multimode W type (doubly clad) plastic optical fiber which takes the characteristic W-shaped index profile designed from a multimode singly clad step index plastic optical fiber upon modification of the cladding ...
