Path loss models based on stochastic rays [PDF]
IET Microwaves, Antennas & Propagation, 2007 In this paper, two-dimensional percolation lattices are applied to describe wireless propagation environment, and stochastic rays are employed to model the trajectories of radio waves. We first derive the probability that a stochastic ray undergoes certain number of collisions at a specific spatial location.

In-body path loss models for implants in heterogeneous human tissues using implantable slot dipole conformal flexible antennas [PDF]
, 2011 A wireless body area network (WBAN) consists of a wireless network with devices placed close to, attached on, or implanted into the human body. Wireless communication within a human body experiences loss in the form of attenuation and absorption.

Path loss models with distance‐dependent weighted fitting and estimation of censored path loss data [PDF]
IET Microwaves, Antennas & Propagation, 2016 Path loss models are the most fundamental part of wireless propagation channel models. Path loss is typically modelled as a (single‐slope or multi‐slope) power‐law dependency on distance plus a log‐normally distributed shadowing attenuation.

Tunable n-path notch filters for blocker suppression: modeling and verification [PDF]
, 2013 N-path switched-RC circuits can realize filters with very high linearity and compression point while they are tunable by a clock frequency. In this paper, both differential and single-ended N-path notch filters are modeled and analyzed.
