Near sputter-threshold GaSb nanopatterning

Proximity field nanopatterning of azopolymer thin films.

A method for inscribing surface relief gratings in azopolymer thin films via proximity field nanopatterning is reported. Azopolymers prepared by ring opening metathesis polymerization were cast as thin films and brought into conformal contact with transparent polydimethylsiloxane phase masks. Irradiation of the film surface through the phase masks induces mass transport of azopolymer that gener...

Efficient Gravity Field Computation for Trajectory Propagation near Small Bodies

We present an approximation scheme for gravitational force near arbitrarily shaped small bodies. The approximation uses polynomial interpolation with an adaptive spatial data structure. This data structure allows us to drive errors in the model to within user defined thresholds. The result is a method that is expected to reduce the run time of trajectory integrations around small bodies without...

Near-field diffractive elements.

A novel near-field imaging system is proposed and simulated. It is seen that a significant improvement in performance in the presence of noise is possible without loss of resolution.
