From: Lithography-free IR polarization converters via orthogonal in-plane phonons in α-MoO3 flakes
a Schematic representation of atomic orientation in the bulk structure of α-MoO3 in xz and yz planes, (b) real and (c) imaginary parts of the dielectric function for α-MoO3. d Schematic illustration of the investigated multilayer structure.
