Theoretical Extension of a Microwave EM Method for Predicting the Terahertz Scattering of Electrically Large Complex Target

Leida xuebao, 2018
Two important issues must be considered when modeling the terahertz (THz) wave scattering behavior using microwave EM methods. The first is the material response characteristics, including the metallic materials that may be beyond the scope of the Drude ...

Very compact millimeter sizes for composite star-forming/AGN submillimeter galaxies [PDF]

, 2017
We report the study of far-IR sizes of submillimeter galaxies (SMGs) in relation to their dust-obscured star formation rate (SFR) and active galactic nuclei (AGN) presence, determined using mid-IR photometry. We determined the millimeter-wave ($\lambda_{\

Wideband Single and Dual Linearly Polarized Magneto-Electric Dipole Array Antennas for 5G/6G Millimeter-Wave Applications

IEEE Open Journal of Antennas and Propagation
A new taper-shaped linearly polarized (LP) magneto-electric (ME) dipole, excited by the U-shaped microstrip line through a coupling slot, is proposed in this paper. An ultra-wide simulated impedance bandwidth of 85% (20.5-50.6 GHz) and 1.5-dB gain
