  • Design and characterization of photonic crystal fiber for sensing applications 
    Morshed, Monir; Arif, Md. Faizul Huq; Asaduzzaman, Sayed; Ahmed, Kawsar (European Scientific Journal, 2015-12)
    A simple structure of Photonic Crystal Fiber (PCF) for gas sensing and chemical sensing has been proposed in this paper. Index guiding properties of proposed PCF have been numerically investigated by using finite element ...
  • Design of single mode spiral photonic crystal fiber for gas sensing applications 
    Islam, Md.Ibadul; Ahmed, Kawsar; Asaduzzaman, Sayed; Paul, Bikash Kumar; Bhuiyan, Touhid; Sen, Shuvo; Islam, Md. Shadidul; Chowdhury, Sawrab (Elsevier, 2017-03-06)
    In this paper, a spiral shape photonic crystal fiber (S-PCF) has been suggested as a gas sensor for detecting toxic or colorless gases as well as monitoring the air pollution by metering gas condensate elements in production ...
  • Highly birefringent single mode spiral shape photonic crystal fiber based sensor for gas sensing applications 
    Islam, Md. Ibadul; Paul, Bikash Kumar; Ahmed, Kawsar; Hasan, Md. Rabiul; Chowdhury, Sawrab; Islam, Md. Shadidul; Sen, Shuvo; Bahar, Ali Newaz; Asaduzzaman, Sayed (Elsevier, 2017-04-21)
    This article represents a gas sensor based on spiral photonic crystal fiber (S-PCF) for detecting harmful or colorless gasses and monitoring air pollution by metering gas condensate elements in production facilities. The ...
  • Investigation of Gas Sensor Based on Differential Optical Absorption Spectroscopy Using Photonic Crystal Fiber 
    Paul, Bikash Kumar; Ahmed, Kawsar; Dhasarathan, Vigneswaran; Al-Zahrani, Fahad Ahmad; Aktar, Mst. Nargis; Shahin Uddin, Muhammad; H.Aly, Arafa (Alexandria Engineering Journal, Elsevier, 2020-12)
    This study presented a novel shape photonic crystal fiber based gas sensor for the first time. Perfectly circular shape air hole are arranged to form core and cladding region. Based on full vector finite element method ...
  • IoT-Based Air Pollution Controlling System for Garments Industry 
    Oyshi, Marzan Tasnim; Bonny, Moushumi Zaman; Zaki, Syed Ahmed; Saha, Susmita (Springer, 2021)
    Environment is changing dramatically due to global warming and environment pollution and leading the next generation toward a vulnerable future. Air pollution is one of the key factors of the unstable environment around ...
  • Proposal of a gas sensor with high sensitivity, birefringence and nonlinearity for air pollution monitoring 
    Asaduzzaman, Sayed; Ahmed, Kawsar (Elsevier, 2016-07-01)
    Flammable or poisonous gasses in the air are capable of destroying a geographical area of causing a fire, fulmination, and venomous exposure. This paper presents a micro-cored photonic crystal fiber based gas sensor for ...
  • Self-powered IoT-Based Design for Multi-purpose Smart Poultry Farm 
    Akhund, Tajim Md. Niamat Ullah; Snigdha, Shouvik Roy; Reza, Md. Sumon; Newaz, Nishat Tasnim; Saifuzzaman, Mohd.; Rashel, Masud Rana (Scopus, 2021)
    The purpose of the present work is to make an IoT-based smart poultry farm system. In this work, the power supply is developed using renewable energy mainly with solar energy and nano-hydro. This IoT-based module helps to ...
