TRANSFER SYSTEM USING MAGNETIC RESONANT COUPLING

WHY?

• No Need of wire.

• decreased amonts of e!cess wirin".

• #dea$ for continos or instantaneos

spp$y of e$ectricity.

• Sa%in" in t&e cost of copper.

• No need to re'wirin" &ome.

• (edction of wastef$ &ardwarecomponents )e.". *isposa+$e Batteries,

• #mpro%e &ose&o$d c$ean$iness.




How?

• S&o$d +e desi"ned in a way t&at t&e fre-encyof t&e a$ternatin" crrent is increased to t&eresonant fre-ency.

•

&e tra%e$$in" crrent indces ma"netic ande$ectric e$ds in t&e indctor and capacitor$oops respecti%e$y w&ic& e!tends p to 5meters arond t&e de%ice.

•

&is ma"netic e$d indces an e$ectric crrentin t&e indctor $oop of any mo+i$e "ad"et&a%in" t&e recei%er coi$ wit& t&e same resonantfre-ency.

Basic &eory.

• &e princip$e of ;%anescent Wa%e 2op$in" e!tends t&e princip$e of ;$ectroma"netic indction.

• ;$ectroma"netic indction works on t&e princip$e of a primary coi$ "eneratin" a predominant$yma"netic e$d and a secondary coi$ +ein" wit&in t&at e$d so a crrent is indced wit&in its coi$s.

• &e resonance comes in and &e$ps t&e e<ciency dramatica$$y +y =tnne$in"= t&e ma"netic e$d to arecei%er coi$ t&at resonates at t&e same fre-ency.3 e%anescent wa%es are prodced w&ic& carry no

• #f a proper resonant wa%e"ide is +ro"&t near t&e transmitter3 t&e e%anescent wa%es can a$$ow t&eener"y to tnne$ to t&e power drawin" wa%e"ide3 w&ere t&ey can +e rectied into *2 power.

•

Since t&e e$ectroma"netic wa%es wo$d tnne$3 t&ey wo$d not propa"ate t&ro"& t&e air to +ea+sor+ed or +e dissipated3 and wo$d not disrpt e$ectronic de%ices or case p&ysica$ injry.
