【 摘 要 】

Silver/silicon dioxide and gold/silicon multilayer imaging structures are shown to have subwavelength imaging performance. The influence of the duty cycle is presented. Imaging possibilities with a slab having isotropic negative effective dielectric constant is also explored. This system may be worthy of an experimental program to establish that subwavelength resolution is practical. Success will lead to a new class of imaging, memory, and interconnection structures.
