Waveform-Selective Devices for Antenna Applications [PDF]

2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020
In this contribution, we investigate several examples of antenna applications of waveform-selective devices, i.e., structures exhibiting different responses depending on the waveform of the incoming waves. In particular, as a first example, we describe an open-ended waveguide capped with an iris band-pass filter loaded with a lumped-element circuit ...

Waveform Selectivity at the Same Frequency [PDF]

Scientific Reports, 2015
AbstractElectromagnetic properties depend on the composition of materials, i.e. either angstrom scales of molecules or, for metamaterials, subwavelength periodic structures. Each material behaves differently in accordance with the frequency of an incoming electromagnetic wave due to the frequency dispersion or the resonance of the periodic structures ...
