On the Differential Input Impedance of an Electro-Explosive Device

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 ...

Phase Corrected H-Plane Horn Antenna in Gap SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

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 ...

Design of active Multiple-degrees-of-freedom electroacoustic resonators for use as broadband sound absorbers

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

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 ...

On the Optimisation of Multi-Degree-of-Freedom Acoustic Impedances of Low-Frequency Electroacoustic Absorbers for Room Modal Equalisation

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

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 ...

Design of an Efficient High Power Electromagnetic Radiator using a Yagi-Uda Antenna Connected to a Switched Ocillator

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 ...

PCB Design and Fabrication for NEMS Applications

Christian Clerc

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 ...

An Improved Formula for the Transfer Impedance of Two-Layer Braided Cable Shields

Nicolas Mora Parra

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 ...

Numerical Simulation of the Overall Transfer Impedance of Shielded Spacecraft Harness Cable Assemblies

Nicolas Mora Parra

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 ...

Feeding structure influence on performance of two UWB antennas near a human arm

Anja Skrivervik, Mohsen Koohestani

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 ...

Mechanical Characterization and Shape Optimization of Fascicle-Like 3D Skeletal Muscle Tissues Contracted with Electrical and Optical Stimuli

Mahmut Selman Sakar

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 ...
