      abstract     = {Encapsulating few-layer graphene (FLG) in hexagonal boron
                      nitride (hBN) cancause nanoscale inhomogeneities in the FLG,
                      including changes in stackingdomains and topographic
                      defects. Due to the diffraction limit, characterizingthese
                      inhomogeneities is challenging. Recently, the visualization
                      of stackingdomains in encapsulated four-layer graphene (4LG)
                      has been demonstratedwith phonon polariton (PhP)-assisted
                      near-field imaging. However, theunderlying coupling
                      mechanism and ability to image
                      subdiffractional-sizedinhomogeneities remain unknown. Here,
                      direct replicas and magnifiedimages of
                      subdiffractional-sized inhomogeneities in hBN-covered
                      trilayergraphene (TLG) and encapsulated 4LG, enabled by the
                      hyperlensing effect,are retrieved. This hyperlensing
                      effect is mediated by hBN’s hyperbolic PhPthat couple to
                      the FLG’s plasmon polaritons. Using near-field
                      microscopy, thecoupling is identified by determining the
                      polariton dispersion in hBN-coveredTLG to be
                      stacking-dependent. This work demonstrates super-resolution
                      andmagnified imaging of inhomogeneities, paving the way for
