Metastructures hold the potential to bring a new twist to the field of spatial-domain optical analog computing: migrating from free-space and bulky systems into conceptually wavelength-sized elements.
A lot of things are harder to do backwards – solving photonics problems is a case in point. “Where the forward calculations are well understood with Maxwell’s equations, solving one instance of an ...
A function machine is a way of writing rules using a flow diagram. The equation \(3h - 6 = 9\) can be shown on a function machine by writing out the functions that have been applied to \(h\) in the ...
