This communication introduces a modified substrate integrated waveguide (SIW), the gap SIW, and deduces an approximate closed-form expression for calculating its effective width, taking into account the fringing and coupling fields around the gap. As an im ...
We present a novel control method achieving stable multiple-degrees-of-freedom electroacoustic resonators. Such broadband absorbers, composed of a feedback-controlled electrodynamic loudspeaker, have many practical applications to real-world acoustic engin ...
Abstract: In this paper, a model for the input impedance of a hot-wire electro-explosive device (EED) based on differential-mode measurements is proposed. The model represents the EED using three transmission line segments in cascade. The characteristics o ...
Low-frequency electroacoustic absorbers have recently been developed as a solution for the modal equalisation. Firstly investigated in waveguides, the technique consists in matching the acoustic impedance at a closed-box loudspeaker diaphragm to the charac ...
We propose in this paper the use of a monopolar version of the Yagi-Uda antenna connected to a switched oscillator (SWO). At the resonance frequency, this antenna offers a higher impedance than, for example, a Half Impulse Radiating Antenna (HIRA), a helic ...
In this project, a resonator was theoretically defined and modelled in an effort to choose appropriate impedance matching between the resonator and outside electronics. Quite Universal Circuit Simulation (QUCS) was used to model the S-parameter of potentia ...
This paper reports a study of the feeding structure influence on impedance matching and system fidelity factor of two loaded UWB antennas when placed near a human arm. To this aim, two identical dielectric loaded versions of the same UWB antenna designs wi ...
In this letter, we propose a formula for evaluating the transfer impedance of two-layer braided cable shields. The proposed formula results from the combination of the model proposed by Vance for the evaluation of the equivalent transfer impedance of a two ...
In this paper, we present general considerations for the application of the multiconductor transmission-line theory for simulating shielded spacecraft harness cable assemblies. Some of the practical issues that occur in the modeling process of various comp ...

In this study, we present a quantitative approach to construct effective 3D muscle tissues through shape optimization and load impedance matching with electrical and optical stimulation. We have constructed long, thin, fascicle-like skeletal muscle tissue ...
