Design and Analysis of Novel Fractal Linear and Planar Array Antennas for Satellite Applications

open access: yesAdvanced Electromagnetics, 2016
This article proposed a new geometric design methodology for the systematic expansion of fractal linear and planar array antennas. Using this proposed geometric design methodology any deterministic polygon shape can be constructed.

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Abduction and Deduction in Dynamical Cognitive Science

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract This paper reviews the recent history of a subset of research in dynamical cognitive science, in particular that subset that allies itself with the sciences of complexity and casts cognitive systems as interaction dominant, noncomputational, and nonmodular. I look at this history in the light of C.S.

Minkowski’s Loop Fractal Antenna Dedicated to Sixth Generation (6G) Communication

open access: yesFractal and Fractional, 2022
In this study, we will discuss the engineering construction of a special sixth generation (6G) antenna, based on the fractal called Minkowski’s loop. The antenna has the shape of this known fractal, set at four iterations, to obtain maximum performance ...

Quad-Band Uniformly Spaced Array Antenna Using Diverse Patch and Fractal Antennas

open access: yesApplied Sciences, 2023
Multi-band antennas have received significant interest because they can support multiple wireless communication services with a single antenna. However, an array antenna consisting of these element antennas can suffer from non-periodic arrangement due to
