Fig. 2: Microwave energy transmission of the shopping-bag EM waveguide.
a, b Test setups using a vector network analyzer (VNA) to measure the energy transmission losses of the WR-284 rigid and shopping-bag waveguides. c Simulation results of the S21 vs. frequency plot as a comparison between the WR-284 rigid and the shopping-bag waveguides. d, e Simulated electric field distributions at the central frequency for the WR-284 rigid and the shopping-bag waveguides, respectively. f Average experimental S21 vs. frequency plot as a comparison between the WR-284 rigid and the fabricated shopping-bag waveguides with deployment tests repeated ten times. Scale bars: 60 mm.
