In this article, we demonstrate a specially designed resonant metamaterial with epsilon-near-zero (ENZ) and nanoantenna to enhance the exposure depth in plasmonic direct writing lithography more than 10 times. The ENZ metamaterial composed of a Ag/Si3N4 multilayer thin film, converts the evanescent field generated by the bowtie aperture nanoantenna to propagating waves with low divergence and high collimation. Deep sub-diffraction limited resolution of less than 65 nm (λ/7) with exposure depth greater than 100 nm is achieved. This work brings plasmonic direct writing lithography one step closer to practical applications.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
