• The addition of quarter-wave plates permits examination using circularly polarized light.
• A major practical drawback to the VLF band is that because of the length of the waves, full size resonant antennas (half wave dipole or quarter wave monopole antennas) cannot be built because of their physical height.
• The reflectors at the ends of the cavity are dielectric mirrors made from alternating high and low refractive index quarter-wave thick multilayer.
• These kits are designed to have a mobile whip screwed on top (a full-length, quarter-wave steel whip is preferred) and mounted on a mast.
• Two common types of waveplates are the "half-wave plate", which shifts the polarization direction of linearly polarized light, and the "quarter-wave plate", which converts linearly polarized light into circularly polarized light and vice versa.

• Some are a quarter wave or more long, which restricts their use to the higher frequencies.
• If the layer's thickness is controlled precisely such that it is exactly one-quarter of the wavelength of the light in the layer (a "quarter-wave coating"), the reflections from the front and back sides of the thin layer will destructively interfere and cancel each other.
• The output inductor of the quarter wave network can be merged with the inductor used to cancel the reactance of the load, by replacing the pair with one inductor with the sum of the two inductances.
• In microwave circuits, impedance inversion can be achieved using a quarter-wave impedance transformer instead of a gyrator.
• For example a quarter wave whip antenna for the SHF band is between 25 and 2.5 centimeters long.

• Success in this task was aided by the missile fuselage profile, which acted as an excellent quarter-wave reflector for 12 m band HF radar.
• A typical RF load is a quarter-wave ground plane antenna (37 ohms with an ideal ground plane).
• In telecommunications, a collinear antenna array (sometimes colinear antenna array) is an array of dipole or quarter-wave antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear; that is, they are located along a common axis.
• Note that to produce a value comparable between differently-fed antennas, radiation resistance is referenced to the (nearly) quarter-wave, zero-reactance, maximum-current value, [...] even when no such current is present on the actual antenna.
