What are the left-handed media and what is interesting about them?

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 lefthanded medium is analyzed. The physics of a perfect lens formed by a flat layer of a left-handed material is considered.

This article aimed at identifying the rate of dissatisfied employees who had left their previous jobs and the main factors which caused their dissatisfaction. In order to collect data for this study a well-structured questionnaire was distributed to 150 employees of different private and public organizations in Bangladesh who already left their previous jobs and 142 usable responses were rec...
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 ...
