Arbitrary multi-bit programmable phases (adapted from [29]). (a) Conceptual illustration. (b) Basic illustration of the vector synthesis method in the complex plane for the generation/analysis of multi-bit phases. (c, d) Equivalent phase coverage at the center angular frequency ω c  = 2πf c and the first harmonic ω c  + ω 0 = 2π (f c  + f 0), respectively, for a 2-bit time-coding sequences with length L = 8.
