A Method for Generating Uniform Fields with Lower Sidelobe Using CMMPTE

In this work, the constrained maximum power transmission efficiency (CMMPTE) is applied to generate the uniform focusing field with lower sidelobe. The three different uniform power transmission scenarios are all achieved using a 31element dipole transmitting array, with different weighted constraints imposed in the target regions for each case. The magnitude of the electric fields in the target regions are all above 3 dB, and the field strength rapidly decreases to below - 20 dB within half a wavelength. Compared to results realized by the timereversal method in the three different target regions, the sidelobe levels of the uniform fields obtained by the CMMPTE all below - $\mathbf{1 8}$ dB, indicating that the transmitted energy is primarily confined within the target regions.
