Analytically Co‐Designed Absorption‐Diffusion Coding Metasurface for RCS Reduction
ABSTRACT This work proposes a novel and simple design method for an absorption‐diffusion metasurface, combining a coding diffusion‐type metasurface with an absorbing layer. The diffusion and absorption properties are obtained through an analytical co‐design methodology derived from a straightforward Smith chart‐based construction.

Thin‐film ferroelectric microcapacitors are analyzed using full‐wave electromagnetic simulations to establish design rules linking material properties, geometry, and electrical performance. The relationships among ferroelectric permittivity, film thickness, dielectric tunability, and coplanar capacitor geometry are established.

Circuit Modelling of Bandpass/Channel Filter with Microstrip Implementation
This paper presents a step-by-step approach to the design of bandpass/channel filters. A 3-pole Chebyshev bandpass filter (BPF) with centre frequency of 2.6 GHz, fractional bandwidth of 3%, passband ripple of 0.04321 dB and return loss of 20 dB has been designed, implemented, and simulated.

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs
Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...
