Artificial Intelligence (AI) has advanced material research that were previously intractable,
for example, the machine learning (ML) has been able to predict some unprecedented …

Within the past a few years, transformation optics has emerged as a new research area,
since it provides a general methodology and design tool for manipulating electromagnetic …

The field of transformation optics shows that media containing gradients in optical properties
are equivalent to curved geometries of spacetime for the propagation of light. Conformal …

The gradient-index (GRIN) Luneburg lens antenna offers significant benefits, eg high
aperture efficiency, low-power, minimal cost, wide beam scanning angle and broad …

Conformal transformation optics is employed to enhance an H-plane horn's directivity by
designing a graded-index all-dielectric lens. The transformation is applied so that the phase …

In the modern world, the ability to manipulate and control electromagnetic waves has greatly
changed people's lives. Novel optical and electromagnetic phenomena and devices will …

The maximum current (critical current) a type-II superconductor can transmit without energy
loss is limited by the motion of the quantized magnetic flux penetrating into a …

We present a new technique for the design of transformation-optics devices based on large-
scale optimization to achieve the optimal effective isotropic dielectric materials within …

Although metamaterials have been widely used for controlling elastic waves through
bandgap engineering, the directed guidance of stress waves in non-periodic structures has …

A circular graded index lens is conformally transformed to an elliptical shape using a closed-
form transformation. The proposed transformation is then employed to compress a Maxwell …
