Abstract: The present application describes an apparatus a non-transitory memory having instructions stored thereon and a processor operably coupled to the non-transitory memory configured to execute the instructions. The executed instructions include extracting eigenvalues for a coupling matrix of a target device. The executed instructions also include extracting a first set of eigenvalues for a coupling matrix of a device under tune (DUT). The eigenvalues of the target device may be different than the first set of eigenvalues of the DUT. The executed instructions further include causing a material removal source to be positioned at a first location of the DUT. The executed instructions even further include causing the material removal source to tune the DUT. The executed instructions yet further include measuring a second set of eigenvalues of the DUT. The executed instructions yet even further include observing an iterative convergence of the DUT and the target device.

Abstract: The present application describes a method of tuning a printed device. The method includes measuring a frequency response of a target device and a device under tune (DUT). The method includes computing, based on the measured frequency response, a coupling matrix for the target device and a coupling matrix for the DUT. The method also includes extracting eigenvalues for the coupling matrix of the target device and a first set of eigenvalues for the coupling matrix of the DUT. The eigenvalues of the target device are different than the first set of eigenvalues of the DUT. The method further includes tuning the DUT with a material removal source. The method even further includes measuring a second set of eigenvalues of the DUT. The second set of eigenvalues is different from the first set of eigenvalues of the DUT. The method yet even further includes calculating a tune path for iterative convergence of the second or a subsequent set of eigenvalues of the DUT with the eigenvalues of the target device.
