  The advent of various wireless technologies have revolutionized the
communication infrastructure and consequently changed the entire world into a
global village. Use of wireless technology has also been made for transmission
of electric power wirelessly. It increases the portability of power systems and
integrates the communication technologies and electric power to the same
platform. This paper presents a comprehensive review and detailed analysis of
various techniques used for wireless power transmission. Feasibility,
implementations, operations, results and comparison among different methods
have also been covered in order to identify the favorable and economical method
for low power and small distance applications.
