where Vi represents the signal strength of electrode i, Z(ω) is the transfer impedance of a BPM pickup electrode depending on the design, I(ω) is the beam spectrum, and s is a sensitivity function. Compared to s, which determines the signal strength on an electrode, we are more conce...
The stacked square patches are used to improve the impedance match. As depicted in Figure 2b, the beam-steering layer comprises four RDSLs, specifically named Unit I to IV. Each RDSL consists of two concentric square loops. The outer loops are printed on the bottom side of substrate 3, ...
Their work demonstrates the advantages of impedance-invariant vector modulation in enhancing stability and isolation, employing novel vector modulator structures for precise phase adjustment. The simplified components and structures, including the vector-sum phase shifter and variable gain amplifier, are ...
