    Design and Modeling of Very Narrow Band-Pass Radio Frequency Filter for Optical Pressure Sensor
    (Institute of Electrical and Electronics Engineers Inc., 2021) Ispak, T.S.; Basarancr, G.; Ceylan, S.; Salmanogli, A.; Gecim, H.S.; 182579; 06.03. Elektrik-Elektronik Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya Üniversitesi
    In this study, an optical pressure sensor is designed to sense a force on the scale of 100 nN. For this purpose, a very narrow radio frequency band-pass filter is designed and modeled to detect the optical pressure force. The center frequency of the filter is fixed in L-band. Thus, by applying an external force, the circuit's characteristics such as scattering parameters and the center frequency of the filter is changed. That is the method particularly employed to sense a very low scale optical pressure. In this study, the open-stub technique is used to design the radio frequency filter and results are compared with the lumped element-based circuit models. Also, the circuit design is simulated in COMSOL Multiphysics, and the scattering parameters are studied. Finally, the circuit is optimized for the specific aim using Advanced Design System software. © 2021 Chamber of Turkish Electrical Engineers.
