  BITS Pilani, HyderabadCampus  A Schottky barrier diode is formed by connecting a metal with a semiconductor.  The semiconductor material of metal generally is chosen from different metals such as molybdenum, chromium, platinum and tungsten.  This diode does not has minority carriers, its speed is much faster, so its reverse recovery time(Trr) is very short and shorter than 10 ns. Mayank Garg Slide 19 Schottky Diode
• 20.
  BITS Pilani, HyderabadCampus  The need of different types of chargers by different manufacturers is totally eliminated  Lower risk of ELECTRICAL SHOCK or shorting.  Convenience  Wireless energy transfer can potentially recharge the mobile phones without chords Mayank Garg Slide 20 Advantages
• 21.
  BITS Pilani, HyderabadCampus  The transmitter and receiver also should be very powerful devices as the distance increases.  Slower Charging.  Wireless transmission of the energy causes some drastic effects to human body, because of its radiation.  More costly.  Practical possibilities are not yet applicable as there is no much advancement in this field. Mayank Garg Slide 21 Disadvantages
• 22.
  BITS Pilani, HyderabadCampus  Thus this paper successfully demonstrates a novel method of using the power of the microwave to charge the mobile phones without the use of wired chargers.  A novel use of the rectenna and a sensor in a mobile phone could provide a new dimension in the revelation of mobile phone.
