Abstract In the quest to realize analog signal processing using subwavelength metasurfaces, in this paper, we present first demonstration of programmable time-modulated metasurface processors based on key properties spatial Fourier transformation. Exploiting space-time coding strategy enables local, independent, and real-time engineering not only amplitude but also phase profile contributing re...

Trigonometric functions are among the most useful functions in the digital signal processing applications. The design introduced in this paper computes the trigonometric functions by means of the systolic arrays. The method for computing these functions for an arbitrary angle, , is the CORDIC algorithm. A simple standard cell is used for the systolic array. Due to the fixed inputs, in some...
