Distribution of metals, PAH's and PCB's in lobsters, mussels, and sediments were used to assess marine environmental quality of the Bay of Fundy. This study demonstrates that the lobster (Homarus americanus) is a better bioindicator for monitoring contaminants in the marine environment and has a greater capacity for the uptake and accumulation of(More)
The ferroelectric material KTaO<sub>3</sub> (KTO) has a very high refractive index, which is advantageous to the photonic crystal (PC) design. KTO polycrystalline crystal has a high extinction coefficient. In this work, we perform a theoretical study of the transmission properties of a PC bandpass filter made of polycrystalline KTO at terahertz (THz)(More)
In this work, the photonic band gap (PBG) structure in a one-dimensional ferroelectric photonic crystal (PC) is theoretically investigated. We consider a PC, air/(AB)<sup>N</sup>/air, in which layer A is a dielectric of MgO and layer B is taken to be a ferroelectric of Ba<sub>0.55</sub>Sr<sub>0.45</sub>TiO<sub>3</sub> (BSTO). With an extremely high value in(More)
In this work, we propose a filter structure using a one-dimensional ferroelectric-dielectric periodic multilayer, air/[(ABA)<sup>N<sub>s</sub> </sup>C]<sup>Np</sup>(ABA)<sup>N<sub>s</sub> </sup>/air, where N<sub>s</sub> and N<sub>p</sub> are the two numbers of periods. Here, B is a dielectric material of SiO<sub>2</sub>, C is the same as B with a different(More)
A fractal multilayer structure made of two dielectric materials can exhibit photonic bandgap (PBG). In this work, with the use of this PBG, we study the transmission properties of periodic triadic Cantor set structures. The results indicate that the structure can be used to design multichannel filters with channel number equal to N-1 for a given number of(More)
