Terahertz (THz) solid immersion microscopy is a
novel THz imaging modality, which provides both a sub- wavelength spatial
resolution and a high energy efficiency, thanks to the absence of
sub-wavelength apertures and probes in an optical scheme. In this work, we
apply the finite-difference time-domain technique for solving the Maxwell's
equations in order to analyze the performance of our original THz SIL
arrangement. Namely, we estimate the theoretical limits for the spatial
resolution and the depth of field of our optical system, as well as specify the
confidential intervals for the alignment of optical elements. The observed
results demonstrate the resolution of 0:15λ and the depth of field of 0:12λ(λ
is an electromagnetic wavelength), justifying advanced performance of our THz
SIL.
