Politicized Framing of the Future: Encouraging Innovation in Mature Ecosystems in the Face of Asymmetric De Alio Entrants

Journal of Management Studies, Volume 63, Issue 6, Page 2894-2926, September 2026.
Abstract Hubs and participants of mature ecosystems increasingly compete with de alio entrants that are hubs of more innovative ecosystems. Prior research shows how these asymmetric de alio entrants frame to win over participants from mature ecosystems and suggests that hubs of these ecosystems should respond by encouraging innovation among ...

How and when remote workdays impact employee daily social need fulfilment

Journal of Occupational and Organizational Psychology, Volume 99, Issue 3, September 2026.
Abstract Hybrid working, as a now‐common flexible work arrangement, transforms how employees connect with each other and requires updated theorizing to understand its social implications. Grounded in interaction ritual theory, we examined how and when remote (vs.

Fully-Metallic Rinehart-Luneburg Lens at 60 GHz

, 2020
In this paper, we present the design of a Rinehart-Luneburg lens antenna operating from 56 to 62 GHz. At these high frequencies, dielectric materials introduce high losses, so fully-metallic solutions are typically preferred.

Scattering of an Electromagnetic Plane Wave by a Luneburg Lens. I. Ray Theory [PDF]

, 2008
For a plane wave incident on either a Luneburg lens or a modified Luneburg lens, the magnitude and phase of the transmitted electric field are calculated as a function of the scattering angle in the context of ray theory.

Applying of Luneburg lens for multi-beam TEM-horn antenna

The Journal of Engineering, 2019
Here, a multi-beam TEM-horn antenna with beam direction is proposed. Presented construction allows obtaining scanning beam and complicated antenna patterns, thus it can be used as substitute of ultra-wideband phased array antennas.

Modified Luneburg Lens: How Well Does It Focus Surface Water Waves?

Fluids
An optical lens focuses light and a similar device can be developed to focus surface water waves. A detailed description of such hydrodynamic lenses is given, for which the focusing is induced by shaping the bathymetry of the bottom.
