Laplace Beamshapes for Phased-Array Imaging

Paul Hurley, Matthieu Martin Jean-André Simeoni

The imaging capabilities of phased-array systems are governed by the properties of their array beamshape, directly linked to the instrument impulse response. To ensure good spatial resolution, beamshapes are designed with a very narrow main lobe, at the co ...

Electromagnetic inspired acoustic leaky-wave antenna

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous st ...

Spatial Multiplexing of QPSK Signals With a Single Radio: Antenna Design and Over-the-Air Experiments

Juan Ramon Mosig, Andreas Peter Burg, Julien Perruisseau-Carrier, Mohsen Yousefbeiki, Andrew Charles Mallory Austin

This paper describes the implementation and performance analysis of the first fully operational beam-space multiple-input multiple-output (MIMO) antenna for the spatial multiplexing of two QPSK streams. The antenna is composed of a planar three-port radiat ...

Compact Microstrip Feedings with an Elevated Ground Plane for Thick Folded SIW

Juan Ramon Mosig, Lei Wang, Qi Wu

Folded substrate integrated waveguide (FSIW) has been proposed for further size reduction, while keeping the advantages of traditional SIW. FSIW-based horn antennas are very promising in millimeter wave applications. To improve the bandwidth and efficiency ...

Design of Compact Air-Vias-Perforated SIW Horn Antenna With Partially Detached Broad Walls

Lei Wang

A novel substrate-integrated waveguide (SIW) horn antenna with partially detached broad walls is designed and analyzed. The conventional SIW horn antenna suffers from narrow-operating bandwidth, which mainly results from the mismatch at the horn aperture b ...

Compact Corrugated Feedhorns With High Gaussian Coupling Efficiency and-60 dB Sidelobes

We demonstrate that very high performance, extremely compact, scalar corrugated feedhorns can be designed and constructed by optimizing the excitation and phasing of the HE11, HE12, and HE13 modes near the throat of the horn while limiting excitation of hi ...

Exotic optical elements generating 2D surface waves

Hans Peter Herzig, Myun Sik Kim, Elsie Barakat, Richa Dubey

We introduce exotic optical elements for 2D surface wave systems hosting Bloch surface waves (BSWs). First, we will study a 2D non-diffracting beam, second, a 2D array of the optical bottle beam via the Talbot effect and third, tight light confinement like ...

Learning to Match Aerial Images with Deep Attentive Architectures

Pascal Fua, Eduard Trulls Fortuny, Hani Altwaijry

Image matching is a fundamental problem in Computer Vision. In the context of feature-based matching, SIFT and its variants have long excelled in a wide array of applications. However, for ultra-wide baselines, as in the case of aerial images captured unde ...
