Abstract The Kalman Filter/Smoother, as a new post-calibration technique, has been
successfully applied for accurate relative complex permittivity ɛ r extraction of planar …

A broadband, stable, and noniterative free-space method is proposed for dielectric constant
determination of low-loss dielectric slabs from reflection-only measurements through simple …

A novel noniterative microwave method is proposed for relative permittivity extraction of solid
samples using thickness-independent reference-plane-invariant (RPI) expressions. The …

This article proposes a convenient technique for determining the permittivity and
permeability of materials placed in a waveguide. Simplicity and repeatability of the method …

This paper presents a novel low-complexity method to characterize the permittivities of low-
loss dielectric slabs at millimeter-wave and sub-terahertz bands. The method assumes …

To determine the complex permittivity of material mounted on the metal surface, the free-
space reflection method is a good candidate due to its advantages of being nondestructive …
