  • This paper reports an experimental observation of irrotational, inviscid, and incompressible electromagnetic power flow within an epsilon-near-zero medium, exhibiting an analogy to an ideal fluid.

  • This paper proposes an unconventional type of antennas that are composed by epsilon-near-zero (ENZ) media. The operating frequencies of such antennas are independent of their geometries, and are determined by material dispersion.

  • Here the authors employ quantum electrodynamics to formulate thermal emission effects in time-modulated media, resulting in innovative thermal emitters. They show that time modulation induces strong field fluctuations in epsilon-near-zero bodies, enabling narrowband emission across the entire range of wavevectors, from near to far-field regimes.

  • Here, the authors demonstrate substrate-integrated photonic doping, enabling the implementation of near-zero-index media within a printed circuit board integrated design. They illustrate the potential by designing and numerically demonstrating a dielectric sensor, an acousto-microwave modulator and a flexible transmission line.

  • Light momentum inside near-zero refractive index materials is analyzed using Abraham–Minkowski discussion. It explains the absence of fundamental radiative processes, of diffraction patterns or Doppler effect inside such materials.

  • The multiple photonic dopants contained in an epsilon-near-zero medium can serve as non-interacting resonators, and offer an opportunity for the independent control of electromagnetic waves at various frequencies.
