With the recent advancement in high-frequency microwave devices and applications, graphene-based antennas are showing real potential due to the unique properties of graphene material and its ability to operate at terahertz communication band (0.1 THz–10 THz). Herein, a very high-gain and ultrawide-band graphene-based patch antenna is proposed with the application of photonic crystal and dielectric grating. The … Continue reading High-gain and ultrawide-band graphene patch antenna with photonic crystal covering 96.48% of the terahertz band

Lung nodule Detection and Classification using Deep Neural Network
Lung nodule detection is a complicated process. It is an interesting topic in the field of biomedical imaging. To detect lung nodules Computer-Aided Detection (CAD) plays an important role. Most of the CAD system consists of a nodule detector and a feature based classifier. In our method the nodule detection part, the CT images processed … Continue reading Lung nodule Detection and Classification using Deep Neural Network
