The geometries of objects are deterministic in electromagnetic phenomena in all aspects of
our world, ranging from imaging with spherical eyes to stealth aircraft with bizarre shapes …

The radiation behavior of the fractional-order, resonant mode within a circular sector cavity
radiator is revealed at first, and then, it is employed to design a novel, planar quasi-isotropic …

Manipulating the spontaneous emission rate of optical emitters with all-dielectric
nanoparticles benefits from their low-loss nature and thus provides a relatively large …

Transformation optics (TO) concept well known for its huge possibility in patterning the path
of electromagnetic waves is exploited to design a beam steering lens. The broadband …

Complex electromagnetic structures can be designed by using the powerful concept of
transformation electromagnetics. In this study, we define a spatial coordinate transformation …

Quasi-conformal transformation optics is applied to design electromagnetic devices for
focusing and collimating applications at microwave frequencies. Two devices are studied …

Conventional periodic structures usually have nontunable refractive indices and thus lead to
immutable photonic bandgaps. A periodic structure created in an ultracold atoms ensemble …

All-dielectric nanoantennas are a promising alternative to plasmonic optical antennas for
engineering light emission because of their low-loss nature in the optical spectrum …

In this paper, based on transformation electromagnetics, the design procedure of a lens
antenna, which steers the radiated beam of a patch array, is presented. Laplace's equation …

The concept of transformation optics (TO) is applied to control the flow of electromagnetic
fields between two sections of different dimensions through a tapering device. The …
