Fundamental Bounds on the Polarizability of Macroscopic Scatterers
Lukas Jelinek, Miloslav Capek
Polarizability predicts how an object responds to an incident electromagnetic field, the interactions between small particles, or the optical forces exerted upon them. Polarizabili…
Physical Bounds on Optical Micromanipulation: Maximal Stiffness in the Dipole Regime
Martin Zlabek, Jakub Liska, Lukas Jelinek +1
Optical trapping and micromanipulation rely on carefully shaped electromagnetic fields to exert precise forces and torques on microscopic particles. Despite their widespread applic…
Multiport Antenna Q-factor
Vojtech Neuman, Miloslav Capek, Lukas Jelinek
This article proposes an estimate of multiport antenna bandwidth based on a generalization of a single-port Q-factor. The explicit derivation is based on converting the stored ener…
Towards Manufacturing-Friendly Shapes in Discrete Topology Optimization
Vojtech Neuman, Miloslav Capek, Lukas Jelinek
This paper deals with shape irregularity issues in discrete topology optimization algorithms whereby the design is created using the automated distribution of material in the desig…
Density-Based Topology Optimization for Characteristic Modes Manipulation
Jonas Tucek, Miloslav Capek, Lukas Jelinek
A density-based topology optimization framework is developed to manipulate characteristic modes of conducting surfaces. The adjoint sensitivity analysis provides an efficient compu…
Characteristic Mode Analysis of Acoustic Scatterers
Lukas Jelinek, Kurt Schab, Viktor Hruska +2
The explicit connection between the transition matrix and boundary element method integral operators is formulated. This enables the calculation of characteristic modes via eigenva…
