Rezumat
Witricity este un concept care defineste o noua tehnologie pentru transferul de informatie/putere intre o sursa si un
receptor fara a folosi conductoare. Pentru a descrie propagarea luminii in ghiduri de unde sau cavitati optice sub influenta
perturbatiilor externe sau a neliniaritatilor, in literatura de specialitate se foloseste teoria modurilor cuplate, dar in transferul prin inductie al puterii, ca urmare a faptului ca se folosesc rezonatoare RLC, teoria circuitelor este mai atractiva. In aceasta lucrare, cele doua abordari sunt aplicate pentru prima data in paralel intr-o problema de transfer de putere prin inductie, si rezultatele dezvoltarilor analitice si ale simularilor sunt comparate pentru a pune in evidenta avantajele si dezavantajele celor doua teorii.

Abstract
Witricity represents a potential technology used to transfer information/power between a source and a receiver without
using wires. To describe the propagation of light in some waveguides or optical cavities under the influence of external disturbances
or nonlinear effects, the coupled mode theory is used, but in wireless power transfer because RLC resonators are used, the circuit
theory is more attractive. In this paper the two approaches are applied for the first time in parallel in a wireless power transfer
problem, the analitical results and the simulation results as well are compared, and the advantages/drawbacks of both theories are
pointed out.
Keywords: witricitywireless power transfercoupled mode theory.
