According to the results, with constant filling factor and changing of elongation of the elements, the width of the band gap has changed and is any change in the magnitude of guiding frequency. However, with constant elongation and increasing of filling factor of elements, the width of the band gap and magnitude of guiding frequencies has decreased. }, URL = {http://opsi.ir/article-1-36-en.html}, eprint = {http://opsi.ir/article-1-36-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2014} }
