Creating a zero-order resonator using an optical surface transformation
F. Sun, X. Ge, S. He
A novel zero-order resonator has been designed by an optical surface transformation (OST) method. The resonator proposed here has many novel features. Firstly, the mode volume can…
Extending the scanning angle of a phased array antenna by using a null-space medium
F. Sun, S. He
By introducing a columnar null-space region as the reference space, we design a radome that can extend the scanning angle of a phased array antenna (PAA) by a predetermined relatio…
Experimentally demonstrated an unidirectional electromagnetic cloak designed by topology optimization
Lu Lan, Fei Sun, Yichao Liu +2
Electromagnetic invisible devices usually designed by transformation optics are rather complicated in material parameters and not suitable for general applications. Recently a topo…
A concentrator for static magnetic field
F. Sun, S. He
We propose a compact passive device as a super-concentrator to create an extremely high uniform static magnetic field over 50T in a large two-dimensional free space from a weak bac…
Confining the light wave by using non-Euclidean transformation optics
F. Sun
A new way to understand why some inhomogeneous dielectric medium can be used for confining the light wave has been given by using non-Euclidean transformation optics. We show that…
Comment on 'Perfect drain for the Maxwell fish eye lens'
Fei Sun
The non-magnetic loss material has been proposed (2011 New J. Phys. 13 023038) to mimic a passive perfect drain in the Maxwell's fish eye lens (MFL). In this comment, we argue that…
