The new paper by Samiul Habib et al. from the Sydney metamaterial fibers group presents a comprehensive overview of how to remove imaging artefacts when using wire media for sub-wavelength imaging. This is particularly important for using these hyperlenses as broadband subwavelength imaging devices. Three methods are presented based on convolution, field averaging, and power averaging. A technique relying on a projection in spatial Fourier space to filter out all ordinary waves overcomes the distortions we observed in our Scientific Reports paper from last year when imaging large objects with sub-wavelength features. The images above were obtained using my Python code – contact me if you might be interested in using it!
