In this paper we show the equivalence of near-field beamforming and backward-wave reconstruction algorithm. The proof is carried out analytically with two different approaches, using the principle of stationary phase from a signal processing point of

Detailed measurements at 60 GHz are carried out to measure the attenuation of an aircraft fuselage and window. The impact of different positions of the transmitter inside the aircraft is investigated. In order to put the measurements in perspective a

In this paper we present certain canonical filter structures that appear to have previously been overlooked. We systematically discuss direct-coupled series- and shunt-resonator-based coaxial filter topologies and elucidate the progression from lumpe

In this paper, we derive a novel condition for single-resonance operation of microwave travelling-wave ring resonators which in contrast to the published condition derived from Su is valid for the ring's field multiplication factor M = S 31 . Unlike

In this paper, we present the derivation of the rotationally symmetric TM Eigenmodes (n = 0) of a coaxial waveguide partially filled with a dielectric. For kρ,1 ∈ ℑ > 0 there is a single solution to the waveguide's characteristic equation which

In this paper, we present a novel time domain technique for measuring the relative permittivity e r of samples based on pseudonoise test signals (M-sequences). Analog correlation is the key enabler of our system, providing high time resolution while
