Wireless Power Transfer via Time Domain Near Field

We seek to develop a wireless power technology capable of focusing
energy  to deeply subwavelength receivers.
Using copper coil arrays (often known as metamaterials in this instance),
we can use a broadband impedance matching technique to optimize power
transfer from a source to receiver.  This includes localization to at
least 4 cm diameter devices.
By localizing the fields in both space and time domain, we believe we can
increase efficiency beyond what is currently possible for wireless power
"mats" (ala powermat corp.).
Our algorithm and scheme combines elements of physics and signal
processing that enable a higher degree of field/power localization than is
currently possible when using the established mechanism and process for
wireless power transfer.
We seek $25K funding in exchange for 2.5% stake in the company.  The
technology is currently a "secret sauce" proprietary idea, but can easily
be extended to full patent protection with investor funding, for
additional stake in the company.

As a first demonstration of time reversed broadband wireless power, we seek to show localized  power transfer to a series of LEDs in  a unique pattern so as to demonstrate the power localization.

Eventually, this technology could be extended to include wireless powering of, for example, cellular telephones or other medium power devices.  Bu using far field electromagnetic wireless power transfer, including our time reversal algorithm, we believe we can provide power in outdoor or indoor environments such that the receivers receive power levels such that  they can be adequately charged in real time.  Our proposed method uses multipath environments in the far field electromagnetic spectrum such that deeply subwavelength focusing can be achieved. In this way, we can achieve power localization to almost arbitrarily small devices.  The limitation on this type of wireless power transfer is such that low (e.g. smoke dector) to medium (e.g. cell phone) power devices are the most obvious application areas.  With furthered research, we believe we can  extend the technology to high power devices.
