MILLIMETER-MILLIMETER-WAVE DOUBLE-MODULATION DOUBLE-RESONANCE SPECTROSCOPY [PDF]
Proceedings of the 2021 International Symposium on Molecular Spectroscopy, 2021 A new millimeter- to millimeter-wave double-modulation double-resonance (MMW-MMW DM-DR) scheme has been applied to record spectra of two astronomically relevant complex organic molecules (COMs), propanal (C2H5CHO) and ethyl cyanide (C2H5CN), to demonstrate advantages of the DM-DR experimental technique.

Millimeter-wave compressive holography [PDF]
Applied Optics, 2010 We describe an active millimeter-wave holographic imaging system that uses compressive measurements for three-dimensional (3D) tomographic object estimation. Our system records a two-dimensional (2D) digitized Gabor hologram by translating a single pixel incoherent receiver. Two approaches for compressive measurement are undertaken: nonlinear inversion

Design of a 2-Bit wide-angle coding metasurface for bistatic RCS reduction
Frontiers in Materials, 2022 A 2-bit wide-angle coding metasurface is proposed to decrease the bistatic radar cross section (RCS) in this study. Each meta-atom of the designed coding metasurface is composed of a wide-beamwidth microstrip antenna whose feeding port is loaded with an ...
