Efficient Beampattern Synthesis for Sparse Frequency Diverse Array via Matrix Pencil Method
Sensors, 2022 Due to the introduction of frequency offsets, the pattern synthesis problem of sparse Frequency diverse array (FDA) becomes more complicated than that of the phased array. A typical way to solve this problem is to use a global optimization algorithm, but

Coupling matrix synthesis of general chebyshev filters [PDF]
MATEC Web of Conferences, 2020 A single optimization algorithm based on SolvOpt that synthesizes coupling matrices for cross-coupled microwave filters is presented. The rules for setting initial values of SolvOpt are proposed to find global minimum of the cost function. SolvOpt method

Synthesis of Inorganic Compounds in the Matrix of Polysaccharide Chitosan [PDF]
Biomimetics, 2021 Data related to the fabrication of hybrid materials based on the polysaccharide chitosan were systematized and reviewed. The possibility of using chitosan as a “host” matrix for in situ synthesis of inorganic compounds for the preparation of various types of composite materials were investigated.

Spatiotemporal Traffic Matrix Synthesis [PDF]
Proceedings of the 2015 ACM Conference on Special Interest Group on Data Communication, 2015 Traffic matrices describe the volume of traffic between a set of sources and destinations within a network. These matrices are used in a variety of tasks in network planning and traffic engineering, such as the design of network topologies. Traffic matrices naturally possess complex spatiotemporal characteristics, but their proprietary nature means ...

Clays as a Host Matrix in the Synthesis of Organic Macrocycles
Chemistry – A European Journal, 2003 AbstractA new approach for the synthesis of amide macrocycles, based on the use of organo‐clay derivatives as controlling template, is proposed as an alternative to the rotaxane method. Dications of p‐xylylene diamine inserted in the clay interlayer space act as molding pillars around which neutral diamine molecules are erected via hydrogen bonding and
