spiral

Assuming the spiral arms are symmetrically designed with an infinite number of turns and are excited in its fundamental balanced mode, two leaky traveling waves propagate outward from the feed location and a perfect magnetic conductor (PMC) wall can then be placed in the middle perpendicular plane of spiral arm, as shown in Figure 2(a).

A single-arm Archimedean spiral antenna designed according to UHF detection requirements is thus developed in this study.

But at the same time, there is little research on the spiral recovery for the UAVs.

Four-arm spiral antenna generally consists of four lines of bent metal inlay on the cylindrical substrate without any grounding.

Kawauchi, Kumaki, and Yashima produced spiral-shaped polymer chains with specific spiral winding directions from inexpensive general-purpose polymers and spiral polymers.

The Spiral Labyrinth Calendar is a tool for self-discovery Anything you can color code--meditations, moods, fertility, paydays, sick days, sobriety--you can track on your calendar.

Developed from the ring-coil source model, a novel model referred to as the "spiral heat source model" is further presented in this study for better thermal analysis and design of the novel pile GHE.

The Spiral will feature a cascading series of landscaped terraces and hanging gardens as its signature element.

To design smart and compact wireless products, we cannot rely on increasing the antenna size to achieve the desired results; therefore, researchers are actively looking for innovative solutions to improve the performance of spiral antennas while keeping the size constant.

Eastern Sheet Metal spiral duct has been AMCA Publication 511 certified since 2010, passing all requirements to bear the AMCA Certified Ratings Seal applying to Air Leakage Ratings.

For multi-tiered product flow, a line of multiple entry and exit conveyors can be added to high-capacity spiral conveyors to allow load induction and divert at several intermediate elevations.

Spiral symbols are one of the oldest geometric shapes, used in everything from cave painting to massive land sculptures.
