We introduce the relativ In Fig. 2 $Q = \sqrt{Q_s^2 +Q_g^2}$ is the efficiency of the resulting force acting on the particle. This graph shows the contribution of each ray incident on a particle at a certain angle. It can be seen that the maximum value of $Q_g$ is approximately at the value of the angle of incidence of $70^\circ$, which shows the need to use high values of $NA$. For comparison, we present graphs for other $n$ in Fig. 3 and 4. -It can be seen that at $n\rightarrow 1$ the required maximum angle of incidence becomes too high, and at $n\rightarrow 1.4$$Q_s$ is equal to or exceeds $Q_g$ in most of the angle range, which indicates the difficulty of obtaining a stable capture. +It can be seen that at $n\rightarrow 1$ the required maximum angle of incidence becomes too high, and at $n\rightarrow 1.4$ $Q_s$ is equal to or exceeds $Q_g$ in most of the angle range, which indicates the difficulty of obtaining a stable capture. ## Force along Z-axis @@ -76,7 +76,7 @@ Thus, the resulting force acting on the particle along the axis $Z$ is determine $$F_Z^\Sigma = \frac{1}{\pi r_{max}} \int_{0}^{2\pi} \int_{0}^{r_{max}} (F_{gZ} + F_{sZ}) r d\beta dr$$ -where $r_{max} = f \tg{\phi_{max}}$. +where $r_{max} = f \tan{\phi_{max}}$.
