It is highly desirable to break the diffraction limit on resolution of optical devices and achieve subwavelength focusing. Here, authors show that curved inhomogeneous reflectors offer a practical method for achieving this goal. The surface profile focusing reflector designed be tangential desired power flow so metamirror can described locally by lossless impedance boundaries easily implemented...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Political culture in Iran, the changes in it, factors causing these changes and their proba-ble outcomes have been of interest to writers and researchers at the present time more than ever; as a result, the concept of political culture, which is a newly developed con-cept in the political studies and research in Iran, is regarded as of great importance in these studies. Similarly, the number of...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Abstract It was shown experimentally that for a 65-fs 17-J pulse, the effect of filamentation instability, also known as small-scale self-focusing, is much weaker than predicted by stationary and nonstationary theoretical models high B-integral values. Although this discrepancy has been left unexplained at moment, in practice no signs may allow breakthrough nonlinear pulse post-compression lase...
We show numerically for continuous-wave beams and experimentally for femtosecond pulses propagating in air, that the collapse distance of intense laser beams in a bulk Kerr medium scales as 1/P;1/2 for input powers P that are moderately above the critical power for self focusing, but that at higher powers the collapse distance scales as 1/P.
This study uses the Qualitative Approach on violence against women, focusing on gender socialization in family. After reviewing the research and review of existing theories, using focus groups interviews, the data is collected among 15 women who have experienced husband's violence and based on grounded theory, the data has been analyzed. At first, base on codings, 42 concepts were made. Afterwa...
Interestingly, focusing your people the power of entrepreneurial thinking that you really wait for now is coming. It's significant to wait for the representative and beneficial books to read. Every book that is provided in better way and utterance will be expected by many peoples. Even you are a good reader or not, feeling to read this book will always appear when you find it. But, when you fee...
