AbstractThis article aims to explore the views of the Turkish elite on the state of polarization in Turkey. By identifying four political frames—namely, harmony, continuity/decline, conspiracy, and conflict—that selected Turkish political and civil society elites use in discussing the phenomenon of polarization in the country through their contributions to a workshop and in-depth qualitative interviews, the article finds that there is a considerable degree of polarization among the Turkish elite regarding their views on the presence of polarization in Turkey. Moreover, this overlaps with the divide between the government and the opposition in the country. An analysis of the justificatory arguments employed in constituting the aforementioned frames shows that, while those elites who deny the existence of polarization seek its absence in essentialist characteristics of society, in reductionist comparisons with history, or in internal/external enemies, those who acknowledge polarization’s presence look for its roots in political and institutional factors and processes. The article highlights how, given the denial of polarization by the pro-government elite and the substantial gap between the two camps’ justificatory narratives, the currently reported high rates of polarization in Turkey can, at best, be expected to remain as is in the near future, barring a radical change in political constellations.

Photonic integrated circuits (PICs) play a key role in a wide range of applications. Very often, the performance of PICs depends strongly on the state of polarization of light. Classically, this is regarded as undesirable, but more and more applications emerge that make explicit use of polarization dependence. In either case, the characterization of the polarization properties of a PIC can be a nontrivial task. We present a way of characterizing PICs in terms of their full Müller matrix, yielding a complete picture of their polarization properties. The approach is demonstrated by carrying out measurements of fabricated PICs.

ABSTRACT Light scattering techniques are used in several oil-in-water monitors, proposed or in existence. Particulate matter which may interfere with these monitors is also frequently found in oily wastes. An analysis is made of the potential of using measurements of the angular intensity distribution of scattered light in conjunction with determination of the state of polarization of the scattered light for discriminating between oil and particulates. The size conditions which apply to the oil droplets and particulates relative to the incident light allow the scattered light angular intensity distribution to be treated as a consequence of a combination of classical diffraction and of geometrical refraction and reflection. The state of polarization of the scattered light for oil droplets is investigated using expressions for the electric field which are approximations to the expressions of the Mie theory. For the particulate matter, the state of polarization is probed on the basis of light reflected from a plane. It is found that it would be difficult to discriminate between oil and particulates using measurements of the angular intensity distribution of scattered light even in conjunction with the determination of the state of polarization of the scattered light in a real life situation.
