The "anti-mirror effect" is a new landscape of the perfect lens that can be employed to make multiple objects appear like only one in the far field, leading to practical applications in lighting systems.

Nov 09, 2010: Our paper, "Experimental realization of a broadband illusion optics device ", has been accepted for publication in Phys. Rev. Lett.

Oct 02, 2010: Our article, "Cloak an illusion", was published in Frontiers of Physics in China.

Sep 27, 2010: Our paper, "A simple design of an artificial electromagnetic black hole", was published in J. Appl. Phys.

Aug 27, 2010: Our paper, "Graded index photonic hole: Analytical and rigorous full wave solution", was published in Physical Review B and selected as "Kaleidoscope".

July 1, 2010: Our paper, "Transformation optics that mimics the system outside a Schwarzschild black hole", was published in Optics Express.

April 29, 2010: Our review article, "Illusion optics", was published in Frontiers of Physics in China.

April 23, 2010: Our review article, "Transformation optics and metamaterials", was published in Nature Materials. <PDF> Copyright NPG

Mar 16, 2010: Our NJP paper on "Electromagnetic gateway" was chosen to be a part of a special collection: The NJP Best of 2009, comprising about 60 papers (4-6 papers in each of NJP's 14 fields) out of about 800 papers publushed in NJP in 2009.

Mar 11, 2010: Our talk on "Non-Euclidean Cloaking for Waves" has been selected in the Image Gallery in March Meeting 2010.

Mar 5, 2010: Our topical review invited by J. Phys. D: Appl. Phys. was published, "Acoustic cloaking and transformation acoustics".

Dec 24, 2009: a preprint of "Transformation optics that mimics the system outside a Schwarzschild black hole" has been posted on arXiv, where we applied the transformation optics to mimic a real black hole system of Schwarzschild form.

Nov 1, 2009: Xiaojiong's work on "transformation media based bending waveguide" was selected as Applied Optics's Cover Story.

Oct 20, 2009: "Electromagnetic gateway" was highlighted by Europhysics News, in Vol. 40 No. 5 Page 08.

Sep 14, 2009: Huanyang Chen joined Soochow University and set up a reasearch group on metamaterials and transformation optics.
