Phase Shifting Holography for THz Near-Field/Far-Field Prediction
By
Progress In Electromagnetics Research Letters, Vol. 44, 15-21, 2014
Abstract
With a view to extending techniques for THz antenna near-field/far-field prediction, this communication derives general analytic expressions for calibrated phase shifting holography (PSH) and introduces a new 120º three-step PSH method that avoids switching off the reference field and has symmetrical performance over the entire complex plane, providing spurious free far-field prediction. Numerical tests with simulated near-field patterns at 372GHz confirm the convenience of the method and give an indication of the precision required for the phase shifts.
