چکیده
We review the intensively discussed ideas about wave propagation and refraction in media where both electric permittivity and magnetic permeability are negative. The criticism against negative refraction as violating the causality principle is considered. Starting from the initial wave equations, refraction of beams at the boundary of a left-handed medium is analyzed. The physics of a perfect lens formed by a flat layer of a left-handed material is considered.

متن کاملWhat definition of information would be emancipatory one?
Background and Aim: Human-information interaction, either in every day life or in research approaches, depends on pre-assumptions about “what information is”. Sometimes this pre-assumptions become axiomtic in a way that we must return to primary concerns about them to explore new social phenomenas. Information as an object is one of pre-assumptions. In this paper, the mentioned pre-assumptions ...
