According to the perspective of the present time, the online news portal holds a major door to that gradually increasing greedy life. So around the globe, the various platform has been developed to fulfill the requirement of mankind. A heavy load of work has been carried out for making this platform autonomous in the English language. That's why the machine learning approach is quite a fully developed field in English in news classification. But it can't be said the same for Bangla language. These put in the inspiration to do a research on this topic. So, here Bangla news which has been collected from newspapers and gathered around to make a Bengali Corpus. After preprocessing the news text, different sorts of procedures to classify the news text using baseline and deep learning models of Machine Learning are applied.

To explore the variation of band gap with the changes of lattice configuration, three different types of configurations, triangular, hexagonal and honeycomb lattice structures for both hole and rod variant have been considered in this study. Moreover, we have presented a comparative analysis of the band gap data for different structures and found a wide band gap in the range of 103.773 THz to 340.91 THz in GaP based photonic crystals. To justify the mechanisms responsible for this band gap, we have analyzed the difference in the concentration factor of magnetic field distribution in the air and dielectric bands. This study includes gap-map for GaP based PCs required to design photonic crystal with a particular band gap at the desired frequency regime. Our study will promote the uses of GaP based PCs in various fiber optics and far-infrared ap...
