The Finite Volume Time-Domain (FVTD) method is an effective full-wave technique which allows an accurate computation of the electromagnetic field. In order to analyze the scattering effects due to electrically large structures, it can be combined with methods based on high-frequency approximations. This paper proposes a hybrid technique, which...

In this paper, a semi-analytical solution for the computation of the two-dimensional Green's function for a cylindrical PEC enclosure containing an arbitrary number of confocal elliptic dielectric layers is provided. The approach relies on an expansion of the Green's function into Mathieu functions, whose coefficients are found in an efficient...

This paper presents a method for sea monitoring based on a low-cost 24 GHz offthe-shelf FMCW radar and an embedded Raspberry Pi PC. The technique relies upon the use of range-Doppler maps, which are obtained through a 2D FFT processing of the acquired scattered data. The resulting insights may offer new possibilities for monitoring and...

An overview of the recent advancements in the development of microwave imaging procedures based on the exploitation of the regularization theory in Lebesgue spaces is reported in this paper. Such inversion schemes have been found to provide accurate results in several microwave imaging scenarios, thanks to the different geometrical properties...

In this paper, a mild data driven inversion technique for microwave imaging applications is proposed. The developed approach relies upon the use of a variable-exponent inversion procedure, in which a-priori information about the class of inspected targets is included through a data-driven regularization term. The developed technique has...

In this article, a new microwave-radar-based technique for short-range detection and classification of multiple human and vehicle targets crossing a monitored area is proposed. This approach, which can find applications in both security and infrastructure surveillance, relies upon the processing of the scattered-field data acquired by low-cost...

A phaseless tomographic method for microwave imaging is presented in this paper. The developed algorithm aims at retrieving the distributions of the dielectric properties of a predefined region under test, starting from amplitude-only electric field measurements. The use of this kind of input data allows cheaper measurement setups that do not...

The subject of this paper is the possible use of a network of microwave sensors to achieve a map of the electromagnetic properties of unknown targets. The basic idea is to use a set of microwave sensors to illuminate a region of interest and to measure the resulting axial component of the electric field. Measurements are then processed by means...

This work deals with the electromagnetic characterization of Carasau bread doughs, in the microwave range region. The microstructure, texture, product quality, and dielectric properties were investigated, jointly with a thorough thermogravimetric analysis. The goal is to link the physical properties with the product quality and to process...

The i-motif is a biologically relevant non-canonical DNA structure formed by cytosine-rich sequences. Despite the importance of the factors affecting the formation/stability of such a structure, like pH, cation type and concentration, no systematic study that simultaneously analysed their effect on the i-motif in vitro has been carried out so...

In this paper, we address the problem of automatic image segmentation methods applied to the partial automation of the production process of a traditional Sardinian flatbread called pane Carasau for assuring quality control. The study focuses on one of the most critical activities for obtaining an efficient degree of automation: the estimation...
