Transmitters for Combined Radio Over a Fiber and Outdoor Millimeter-Wave System at 25 GHz
IEEE Photonics Journal, 2020 In the modern wireless networks, millimeter-wave radio-frequency (RF) bands are becoming more attractive as they provide larger bandwidth and higher data rates than the today-used systems operating at frequencies below 6 GHz.

Quantum scalar field in FRW Universe with constant electromagnetic background [PDF]
, 1997 We discuss massive scalar field with conformal coupling in Friedmann-Robertson-Walker (FRW) Universe of special type with constant electromagnetic field. Treating an external gravitational-electromagnetic background exactly, at first time the proper-time

Geometric entropy and edge modes of the electromagnetic field [PDF]
, 2015 We calculate the vacuum entanglement entropy of Maxwell theory in a class of curved spacetimes by Kaluza-Klein reduction of the theory onto a two-dimensional base manifold.

ELECTROMAGNETIC FIELDS ON FRACTALS [PDF]
Modern Physics Letters A, 2006 Fractals are measurable metric sets with non-integer Hausdorff dimensions. If electric and magnetic fields are defined on fractal and do not exist outside of fractal in Euclidean space, then we can use the fractional generalization of the integral Maxwell equations. The fractional integrals are considered as approximations of integrals on fractals. We

Ground‐State Chemical Reactivity under Vibrational Coupling to the Vacuum Electromagnetic Field
Angewandte Chemie, 2016 The ground‐state deprotection of a simple alkynylsilane is studied under vibrational strong coupling to the zero‐point fluctuations, or vacuum electromagnetic field, of a resonant IR microfluidic cavity. The reaction rate decreased by a factor of up to 5.

Controlling Electromagnetic Fields
Science, 2006 Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...
