Power deposition increases with the static magnetic field strength. In this work, a microstrip array with tilted elements is built and the electric field E and magnetic field B1+ are simulated using FDTD method. Their ratio E/B is used to predict the power deposition for two type of different arrays: microstrip array with regular elements and tilted elements. Results show that using the tilted array, coil efficiency and decoupling between elements can be increased. The reduction in E/B ratio indicates possible reduction in power deposition.
