An apparatus includes a near-field transducer (NFT) of a heat-assisted magnetic recording head. The NFT includes a substantially C-shaped portion and a peg portion extending from the substantially C-shaped portion. A planar member is disposed adjacent the NFT. The planar member includes a bottom surface configured to support surface plasmon polaritons (SPPs) that resonantly excite the NFT. A barrier member is installed within the planar member and is arranged to encompass at least a tip portion of the peg.
