Fig. 3: High-Q GMR properties related to diagonal nanoholes area conservation in supercells.

a, d, h, k illustrate four distinct structural configurations for supercells: a features a diagonal circular hole area that matches in area with a square hole, d maintains equal sizes for both square holes while varying those for circular holes, h presents inconsistencies among sizes across four nanoholes devices, k shows four holes converging towards or diverging from the center of the supercell. b, e, i, l depict variations in Q-factor and wavelength associated with parameters R and R2. Herein, d = \(\frac{\sqrt{2}{\rm{P}}}{4}\) in (b, e, i), d*=d-10\(\sqrt{2}\) in (l). c, f, j, m display eigenfield distributions corresponding to the two ultrahigh-Q GMRs
