This article aims at discussing computational approach to design magnet-free nonreciprocal metamaterial. Detailed mathematical derivation on floquet mode analysis is presented for Faraday and Kerr rotation. Non-reciprocity in the designed metasurface

Reciprocity is a fundamental principle follows the time reversal symmetry of physics. However, many practical applications require breaking time reversal symmetry, hence, are called nonreciprocal. This article aims at discussing time reversal symmetr

Full-rate is very important in any data transmission coding. For transmitting data at low bit rate than full-rate code, higher modulation scheme is required. But it is impossible to design full rate orthogonal designs with complex constellation for m

We demonstrate the design and simulation of intense light beam (ILB) achieved by concave microlens engraved lenticular fibers. Both single and multiple microlenses of spherical and elliptical shapes have been incorporated just inside the fiber core.

This paper demonstrates the characterization of femtosecond laser filamentation in soda-lime glass. We achieved femtosecond pulse filamentation of variable height and width by focusing the femtosecond laser beam in different layers inside the sample

In this paper, we report the formation of periodic array of micro/nano-scale holes/voids on the surface of and inside Al 2 O 3 -coated boro-aluminosilicate glass by means of single pulse femtosecond laser irradiation. The lowest diameter of the nano-
