On-Wafer Calibration Algorithm for Partially Leaky Multiport Vector Network Analyzers [PDF]
, 2005 A new solution for multiport vector network analyzer calibration is presented in this paper. The error model is divided in two separate leaky halves, each of them with crosstalk terms, but without the leakage between the two sides.

2014 8th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2014 In the last years, the number of studies carried out in the field of acoustic metamaterials has significantly increased. In year 2009, our group proposed a concept of acoustic composite right/left hand transmission line (CRLH-TL) metamaterial, consisting of a waveguide periodically loaded with membranes along the duct, and transverse open channels ...

The nature of radiation from leaky waves on single- and double-negative metamaterial grounded slabs
, 2004 In this work we investigate the dispersion and radiation properties of leaky waves on metamaterial grounded slabs. A simple analysis of the dispersion equation of TE and TM waves supported by such structures reveals that leaky waves of only the proper ...
