Test mirror symmetry with Bloch-periodic boundaries at the zone edge. This exercises the bug fix from issue #132: eikna[d] must be computed using user

Test two mirror symmetries (X and Y) with Bloch-periodic boundaries at the zone edge. With Mirror(X) + Mirror(Y), gv is halved in both directions. k_x

Computes the transmission spectrum of a plane wave propagating through a Kerr medium. Args: k: strength of Kerr susceptibility.

Return a list of times spent by each process for a type of work `time_sink` which is the same as for `mean_time_spent_on`.

Transforms `epsilon`, `mu`, and `sigma` of any [susceptibilities](#susceptibility) by the 3×3 matrix `m`. If `m` is a [rotation

Computes the Poynting flux in a single-mode waveguide at two locations (5 and 10 μm) downstream from the source given the gri

So that we can make sure to delete everything... for mu=1 non-PML regions, H==B to save space/time - don't delete twice!

Calculates the VJP for a given set of forward and adjoint fields.

Computes the time spent by each MPI process actively working.

Initializes the callable JAX function and registers its VJP.

Makes an array have at least the specified number of dimensions.

Runs adjoint simulation, returning design region fields.

Set CPU to flush subnormal values to zero (if iszero == true). This slightly reduces the range of floating-point numbers, but can greatly increase

|c|^2

note that the components where->c indicate the direction of the force to be computed, so they should be vector components (such as Ex, Ey, ... o

add a polarization to the list if it is not already there

Add a new verbosity flag to be managed. `cvar` should be some object that has a `verbosity` attribute, such as `meep.cvar` or `mpb.cv

Given zero or more step functions, evaluates them only for times after all of the sources have turned off.

Given zero or more step functions, evaluates them only for times after a $T$ time units have elapsed from the start of the run.

this function should ordinarily not be called directly; instead it should be called via require_component, since only require_component knows what oth
