Optical galleries of dielectric rings: antipode to whispering gallery modes
A. P. Chetverikova, M. S. Sidorenko, K. B. Samusev +2
A general picture of photonic eigenmodes of dielectric rings with a rectangular cross section is presented, which is fundamentally different from those of whispering gallery modes…
Density of photonic states in aperiodic structures
Vladislav A. Chistyakov, Mikhail S. Sidorenko, Andrey D. Sayanskiy +1
Periodicity is usually assumed to be the necessary and sufficient condition for the formation of band gaps, i.e., energy bands with a suppressed density of states. Here, we check t…
Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
On the existence of pure, broadband toroidal sources in electrodynamics
Adrià Canós Valero, Dmitrii Borovkov, Mikhail Sidorenko +6
Multipoles are paramount for describing electromagnetic fields in many areas of nanoscale optics, playing an essential role for the design of devices in plasmonics and all-dielectr…
Observation of an accidental bound state in the continuum in a chain of dielectric disks
M. S. Sidorenko, O. N. Sergaeva, Z. F. Sadrieva +4
Being a general wave phenomenon, bound states in the continuum (BICs) appear in acoustic, hydrodynamic, and photonic systems of various dimensionalities. Here, we report the first…
Two-Scale Approach to an Asymptotic Solution of Maxwell Equations in Layered Periodic Media
Maria V. Perel, Mikhail S. Sidorenko
An asymptotic investigation of monochromatic electromagnetic fields in a layered periodic medium is carried out under the assumption that the wave frequency is close to the frequen…
