Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm
Jan David Fischbach, Fridtjof Betz, Lukas Rebholz +6
The transition matrix (T-matrix) is a complete description of an object's linear scattering response. As such, it has found wide adoption for the theoretical and computational desc…
Uncovering hidden resonances in non-Hermitian systems with scattering thresholds
Fridtjof Betz, Felix Binkowski, Jan David Fischbach +5
The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non-Hermitian systems are referred to as scattering thresholds. Close to these branch p…
Measuring the electromagnetic chirality of 2D arrays under normal illumination
X. Garcia-Santiago, S. Burger, C. Rockstuhl +1
We present an electromagnetic chirality measure for 2D arrays of subwavelength periodicities under normal illumination. The calculation of the measure uses only the complex reflect…
