    Design of microstrip ultra wide band antenna with two notch filters for wireless communication by Abdulhasan, Raed Abdulkareem

    Published 2015
    “…In order to add reconfigurable characteristics to the patch antenna, two copper strips are putted on the slots to represent the ON and OFF switching status of an ideal Pin diode. By using this simple switching technique, the current distribution of the patch changes and enables the antenna to have four modes of operation. …”

    Novel opto-electronic and plastic fibre sensors by Ioannides, Nicos

    Published 1998
    “…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”
