High-Q electromagnetic filter in the X-Ku band based on a periodic defective structure RHM/ENG [PDF]
EPJ Web of ConferencesIn this work, we use the Transfer Matrix Method (TMM) to study a one-dimensional (1D) defective structure composed of N periodic cells. Each cell consists of a right-handed material (RHM) transmission line segment coupled to a transmission line resonator

An extension of the RiMAX multipath estimation algorithm for ultra-wideband channel modeling
EURASIP Journal on Wireless Communications and Networking, 2018 This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not
