Motivation:

• QTBM is a highly stable and fast way to solve for device modes
• System block matrices can be reduced from thousands of rows to tens of rows

Approach:

• System is filtered to include only degrees of freedom that contribute to propagating modes
• Using ballistic QTBM solution, self-consistent scattering calculations are performed with low rank matrices

Results:

• Elastic scattering low rank solution shows low error when compared to full basis solution
