Er. Mendez et al., ON THE EQUIVALENCE BETWEEN THE ILLUMINATION AND COLLECTION MODES OF THE SCANNING NEAR-FIELD OPTICAL MICROSCOPE, Optics communications, 142(1-3), 1997, pp. 7-13
The equivalence between the illumination and collection modes of the S
canning Near-Field Optical Microscope (SNOM) is established based on t
he reciprocity theorem for electromagnetic fields. This equivalence ho
lds provided that the sample and the optical elements involved are lin
ear and characterized by symmetric constitutive tensors. (C) 1997 Publ
