Microwave wedge absorber design using rice husk - An evaluation on placement variation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
Placement variation is one example of parameters
that critically affects the performance of RF absorbers. In this
work, four designed variation patterns - W, X, Y, and Z were
discussed to compare the reflectivity (Sll) ...
