Literature Review Title: A Brief Overview of Wireless Power Transfer Techniques 
Chapter Title:  Introduction 
1. Abstract of Cited Paper (BIB001):  In this paper, we present the concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the cost, transmission and distribution losses. This concept is known as Microwave Power transmission (MPT). We also discussed the technological developments in Wireless Power Transmission (WPT) which are required for the improment .The components which are requiredfor the development of Microwave Power transmission(MPT)are also mentioned along with the performance when they are connected to various devices at different frequency levels . The advantages, disadvantages, biological impacts and applications of WPT are also presented.

Literature Review:
The transmission of energy without cords with the intent of charging or supplying power to a remote electronic device has been underway since the time of Tesla. One of Tesla's ambitious goals was to be able to demonstrate a system capable of worldwide distribution of wireless power BIB002 . The lack of funds together with the primitive technology caused the idea to be abandoned for many years since then. Interest in this field has resurfaced recently mainly due to the advent of mobile electronic devices that are constantly on the move and need to be frequently charged. A successful demonstration of wireless power transfer (WPT) was performed in 2007 by a team of researchers from the Massachusetts Institute of Technology (MIT). They were able to light a 60-Watt incandescent bulb located at a distance of two meters from the source without using wires BIB001 . The intent of wireless power transfer is to move electric charge stored in a reservoir to a distant location without the use of transmission cables. Such a system will increase the portability of light electronic devices and free users from the tedious task of transporting power cords. Since our society is already familiar with the concept of wireless communication provided by cellular phones and wireless local area networks, the obvious question to ask is what is preventing us from hauling energy wirelessly?
