Optimal Planar Electric Dipole Antenna
Considerable time is often spent optimizing antennas to meet specific design metrics. Rarely, however, are the resulting antenna designs compared to rigorous physical bounds on those metrics. Here we…

Kirigami Metamaterials for Reconfigurable Toroidal Circular Dichroism
The ancient paper craft of kirigami has recently emerged as a potential tool for the design of functional materials. Inspired by the kirigami concept, we propose a class of kirigami-based…

Chirality-dependent electromagnetically induced transparency based on a double semi-periodic helix metastructure
A chiral metastructure composed of spatially separated double semi-periodic helices is proposed and investigated theoretically and experimentally in this Letter. Chirality-dependent…

On the electromagnetic self-force of a point charge
We calculate the self-force of a point charge in rectilinear motion, using a local method and compare our results with those from the literature.

Which part of a chain breaks
This work investigates the dynamics of a one-dimensional homogeneous harmonic chain on a horizontal table. One end is anchored to a wall, the other (free) end is pulled by external force. A…

Image Charges Re-Imagined
We discuss the grounded, equipotential ellipse in two-dimensional electrostatics to illustrate different ways of extending the domain of the potential and placing image charges such that homogeneous…

Analogy between thermal emission of nano objects and Hawking's radiation
We analyze in this work some analogies between thermal emission of nano objects and Hawking's radiation. We first focus on the famous expression of the black hole radiating temperature derived by…

Backward in time problem of a double porosity material with microtemperature
In the present study we consider the theory of thermoelastodynamics in the case of materials with double porosity structure and microtemperature. This study is devoted to the investigation of a…

Negative refraction of Lamb modes: A theoretical study
This paper provides a theoretical investigation of negative refraction and focusing of elastic guided waves in a free-standing plate with a step-like thickness change. Under certain conditions, a…

Uniformly-moving non-singular dislocations with elliptical core shape in anisotropic media
To allow for `relativistic'-like core contraction effects, an anisotropic regularization of steadily-moving straight dislocations of arbitrary orientation is introduced, with two scale parameters…

Su-Schrieffer-Heeger Model Inspired Acoustic Interface States and Edge States
If a full band gap closes and then reopens when we continuously deform a periodic system while keeping its symmetry, a topological phase transition usually occurs. A common model demonstrating such a…

Engineering separatrix volume as a control technique for dynamical transitions
Dynamical transitions, such as a change from bound to unbound motion, often occur as post-adiabatic crossings of a time-dependent separatrix. Whether or not any given orbit will include such a…

Observation of acoustic spin
Unlike optical waves, acoustic waves in fluids are described by scalar pressure fields, and therefore are considered spinless. Here, we demonstrate experimentally the existence of spin in acoustics.…
