Humanitarian demining is a very urgent and important task for many countries and many techniques are proposed for its solution [1]. We have developed a bistatic GPR system using an Optical Electric Field Sensor (OEFS) as a receiver for landmine detection [2]. This system has two unique features, one is that it is a bistatic radar and the other one is to use a OEFS as a receiver. Therefore, it i...

This paper presents a novel low-profile antenna with a broadside radiation. The proposed design strategy consists in modifying the layout of a classical Vivaldi antenna, thus resulting in compact dimensions and a broadside radiation pattern. Two different ways of implementing the proposed design approach are presented and discussed. More specifically, experimental data referring to two prototyp...

The paper describes the design and the experimental verification of three types of wideband antennas. Attention is turned to the bow-tie antenna, the Vivaldi antenna and the spiral antenna designed for the operation at millimeter waves. Bandwidth, input impedance, gain, and directivity pattern are the investigated parameters. Antennas are compared considering computer simulations in CST Microwa...

This review was written with a dual purpose; on the one hand, to collect all topics dealt during conference “Advances in Singular and Degenerate PDEs”. For this reason, first part of work, abstracts lectures workshop are shown. On other as well workshop, work is way celebrate career Professor Maria Agostina Vivaldi. Vivaldi’s long her hence highlighted work; moreover, some more recent results o...

We report the first conformal ultra-wide band (UWB) array on a doubly curved surface for wide angle electronic scanning. use quadrilateral mesh as basis systematically arraying UWB radiators arbitrary surfaces. A prototype consisting of 52 element, dual-polarized Vivaldi arranged over 181 mm diameter hemisphere is developed. The antennas and SMP connectors are 3D printed out titanium to allow s...
