Metamaterial-Inspired Directive Radiators and Scatterers
Hosted By: Photonic Metamaterials Technical Group
04 May 2022 11:00 - 12:00
Eastern Time (US & Canada) (UTC -05:00)The introduction of metamaterials and metamaterial-inspired structures has led to a wide variety of advances within research and application areas treating structures that radiate (e.g., radio frequency antennas) and scatter (e.g., optical nano-antennas). They have enabled paradigm shifts in terms of our understanding of how electromagnetic devices and systems operate and our expectations of their performance characteristics.
A variety of metamaterial-inspired, near-field resonant parasitic (NFRP), electrically small antennas and nano-antennas have been developed that exhibit unidirectional directivity and multifunctional performance. Their physics and engineering is achieved by combining multiple NFRP elements with simple excitation mechanisms. Higher directivity, in particular, is obtained by simultaneously exciting balanced electric and magnetic multipoles. Examples ranging from passive and active Huygens dipole to superdirective multipole antennas and nano-antennas will be reviewed.
What You Will Learn:
- The electromagnetic theory and practical engineering of unidirectional radiators and scatterers
- Examples of multipole constructs that achieve exceptional and superdirective performance
- Practical issues that must be addressed to further advance the designs and their real world applications
Who Should Attend the Webinar:
- Theoretical and applied electromagnetics researchers and practitioner
- Theoretical and applied photonics researchers and practitioner
