Researchers Hope to Expand Functions of Time Reversal Physics
Within the next five years, it may be possible to charge a cellphone without knowing where it is and destroy tumors no matter how deep they are within the body, using research conducted at the University of Maryland.
Through an age-old technique called time reversal, a team of professors discovered how to communicate â€” by transmitting power, sound or images â€” in any direction rather than merely across a straight line using electronic magnetic pulses. The team found they could transmit power, such as by charging a cellphone, without knowing an objectâ€™s location or disturbing its surroundings. The research â€” which will be published in the next two months â€” has been in the works for two years.
