“…Very good agreement is observed by comparing the numerical results using the approaches proposed in the paper and the corresponding solutions in Ref. [11] for a dielectric cylinder illuminated by a plane wave. To discuss the trapping of chiral particles, the time-averaged Lorentz force density distributions of a single chiral cylinder, and a dielectric cylinder coated by the chiral medium contributed by bound charges and currents, are simulated.…”

“…In recent years, optical forces [1,2,3,4,5,6,7,8,9,10,11,12] in different structures and devices have been a subject of great interest because of theirs application in optical tweezers [2,3,4], tractor beams [5], etc. Most of these studies have been focused on the structures composed of passive materials [3,4], whereas forces on active media have received little attention.…”

“…Because there is no available analytical approach for objects of complicated shapes, some numerical approaches, such as the finite-difference time-domain (FDTD) method [11,24,25,26,27,28], has to be employed. For the analysis of electromagnetic waves and optical forces on effective electric or magnetic dispersive particles [12], not dielectric or metal particles, the Lorentz force formula incorporated with the FDTD method for conventional nonchiral particles has been reported [11].…”

By introducing the effects of bound electric and magnetic charges, the mechanical interaction between waves and a chiral cylinder is investigated with the auxiliary differential equations finite-difference timedomain method. The trapping Lorentz force density distributions of an active chiral cylinder, as well as a core-shell cylinder consisting of a chiral shell and a dielectric core illuminated by a normally incident plane wave are simulated. Numerical results show that the working principle is based on gradient forces generated by the continuously coupled cross-polarized waves. This finding may provide a promising avenue in chirality detection and sorting chiral particles from achiral ones.

We review the combinations of optical micro-manipulation with other techniques and their classical and emerging applications to non-contact optical separation and sorting of micro- and nanoparticle suspensions, compositional and structural analysis of specimens, and quantification of force interactions at the microscopic scale. The review aims at inspiring researchers, especially those working outside the optical micro-manipulation field, to find new and interesting applications of these methods.

The propagation matrix method and the Maxwell stress tensor are developed to calculate radiation pressure on an inhomogeneous active chiral structure. Based on boundary conditions, a 4 Â 4 propagation matrix connecting two forward and two backward plane waves in adjacent chiral media is derived. This propagation matrix method allows us to access the net, co-and cross-polarized radiation pressure, which are expressed by coand cross-polarized reflection and transmission coefficients, exerted on magnetoelectric coupling inhomogeneous chiral slabs via the derivation of the Maxwell stress tensor for arbitrary polarized plane waves incidence. The accuracies of the methods are examined using the finite difference time domain method and the Lorentz force densities. The radiation pressure on a homogeneous or inhomogeneous active chiral slab affected by the angle of incidence, thickness, chirality parameter, and polarization states of incident waves are investigated. This work is believed to provide insights for detecting chirality parameters of inhomogeneous materials by optical forces.chiral, Maxwell stress tensor, optical forces, propagation matrix method, radiation | INTRODUCTIONRecently, optical pulling forces have stimulated intense interests in the fields of physics, mechanics, biology, and chemistry. [1][2][3][4][5][6][7][8][9][10][11][12][13] The pulling forces can be realized by using tractor beams or on various medium structures. Some effort has been devoted to studying negative optical forces on chiral structures. [4][5][6][7][8][9][10][11][12] Horai et al. formulated an optical force under electronic resonance to enhance the optical force and realized the separation of nanometer-sized chiral molecules. 4 Wo et al. investigated the optical forces induced by a plane wave on two chiral particles coupling with each other via evanescent near fields by using numerical and analytical methods. 12 Nevertheless, further studies on the complex mechanism of optical forces on inhomogeneous chiral structures are necessary.Chiral media can be classified into natural chiral medium, 14 artificial chiral structures, [15][16][17][18] and effective chiral medium. 19,20 Chiral structures with gain, instead of loss, are called active chiral structures. Though the majority of chiral media are passive, green fluorescent proteins, 14 active chiral metamaterials, 15 and chiral functional polymers, 16 and so forth, might be active chiral media.
