Design of the XX incorporates a left-right asymmetric post shape that reduces the risk of incorrect assembly

The asymmetric post shape combined with a custom direct current (DC)-biased step AC waveform created a check valve effect for large particles.

Anisotropy becomes severe for arrays with unequal axial and lateral gaps between obstacle posts and highly asymmetric post shapes.
:
We find that asymmetric post shapes can cause a severe increase in anisotropy.
:
Post shape Anisotropy, A
Circular 3.1 × 10−7
Square 2.1 × 10−6
Equilateral triangle 3.2 × 10−3
We see that highly asymmetric post shapes, such as the right triangle, display anisotropy an order of magnitude higher than the maximum due to the parallelogram layout with circular posts.

LATERAL DISPLACEMENT ARRAY FOR MICROFILTRATION
:
As shown in FIG. 4A, when a post has a vertically asymmetric post shape (e.g., a tapered or conical shape) there are two different gap sizes between the posts.

Lateral displacement array for microfiltration
[0016] FIG. 4A provides a side view representation of conical posts with parameters for vertically asymmetric post designs; FIG. 4B provides a side view of trapezoidal or truncated conical shape; and FIG. 4C provides a side view of a pseudo-parabolic post.
