We propose a dual circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed antenna with wide axial ratio (AR) beamwidth, which can generate the right-hand CP (RHCP) or left-hand CP ...

In Fourier transform infrared (FTIR) spectral imaging spatially distributed spectra of 2D surfaces are registered simultaneously using FTIR spectrometers equipped with array detectors. Scanning ...
